Since you’re using external sites to help you pick cards, I assume you also know that Warrior is the worst possible arena class to choose right? Do you just do it intentionally as some kind of challenge to yourself?
It’s not actually the worst class anymore, that’s likely Hunter or Priest. The LoE cards (and losing the TGT offering bonus on Bolster) actually helped a lot and the class is more mid or mid-bottom tier. I ended the LoE era with a 4.86 average for Warrior, which makes it my 4th best class and pretty close to my overall average for winrate.
But to a certain extent I do pick worse classes to change things up, or when I have multiple quests to clear. Plus playing as unpopular classes can both give me an edge as opponents often mis-play out of sheer unfamiliarity facing Warriors and help me play against other Warriors later (6-1 record v Warriors in LoE! Curse that one loss).
Looking at my stats, I could probably up average wins to 5.5 - 6 by always going with the best class offered (those 1 and 2 win runs really bring down the mean) but I like the variety. The only class I completely avoid is Hunter.
And really, at 7+ wins as a Mage/Rogue/Paladin you’re just lost in the crowd. 7+ win Warrior, my opponents are needing a change of pants before the mulligan is over.
Priest is a contender for worst class, but I honestly think Warlock and Shaman are both worse. Shaman is just awful unless you both are extremely good at deckbuilding and extremely lucky. There’s just a whole lot of total garbage there, and many of the cards that are good need other cards to work well. Sure, Lightning Storm is awesome, but if you don’t get it there’s not that much to bank on.
Warrior, by comparison, has some pretty good tools, particularly at common. War Axe, Obsidian Destroyer, Death’s Bite, Fierce Monkey, Kor’Kron, Execute, and others are really solid. It’s not a good class (the “good” classes are, in this order, Rogue, Mage, Paladin, Druid), but it’s not the worst by far.
Exactly, a class’ power in the arena comes from a) it’s hero power and b) the class commons and rares (with extra weight on the quality of the class cards most recently released). I doubt it’s a coincidence that all the ping classes are on your list.
And I think the number of really bad class commons are a better measure of a class’ Arena power than average quality or quality of the best class commons. I’d much rather draft for a class that had commons ranging from meh to good, than awful to awesome.
I do think you’re selling the Warlock short by ranking it below Priest. The Warlock hero power is extra expensive and can never affect the board (if I’m tapping before turn 6ish things are going bad) but it lets you draft very aggressively without worrying about the late game. And while the average quality of Warlock class commons is somewhat lower than average there are very few unplayably bad Warlock cards below epic.
If I rank all the classes I actually play in Arena (I completely avoid Hunter and don’t play Priest that much) Warlock is my #3 or #4 class, depending on the current set. And if I could actually get good results with Paladin (I haven’t been decent with Paladin since GVG) that’d drop Warlock to solidly middle of the pack.
Arena would be a much better mode if rares and epics were much less rare and epic. I think you should probably have 5-10 rares and 3-5 epics in a deck. It would increase the variety of gameplay, and there’s really no reason to correlate drop rates with arena construction.
The batch of changes we’ve just seen to existing cards - that’s it, right? Is it safe to start disenchanting cards?
I was so excited when my first free OG pack had two legendary glows.
Dust is dust I guess 
So…then fix that shit already? It’s been a problem for 2 years. Seems like a lame excuse. If you have a card that’s broken because something else is broke, fix the broken shit or fix the card until you fix the broken shit.
You could choose not to disenchant any GvG duplicates if you have a better opinion of Blizzard than I do and think they might actually try to balance GvG instead of leaving it as a Doctor Boom infested shithole, but everything else is likely stay as it is for years.
Just Standard; does not need to be ranked. Did mine in casual.
Anyway, I opened 72 packs today (no pre-order - all bought with gold + the 13 free packs). Of those 360 cards, a whopping 174 (48.3%) were auto-disenchanted as extras, producing 1330 dust.
Of the remaining 186 usable cards I got, the breakdown was:
103 Common (55.4%)
65 Rare (34.9%)
15 Epic (8.1%)
3 Legendary (1.6%): Yogg-Saron, Hope’s End (my first one, whoo!), Malkorok, and the dreaded Boogeymonster
Also got quite a few golden cards in the batch - I think I remember reading that they upped the drop rate for goldens. A nice touch; I like the pretty animations.
Already built a casino Mage deck around Yogg. Definitely not the most practical deck in the world, but it’s fun as hell to drop him down and watch the fireworks. Been getting a pesky tendency to cast Astral Recall though, and I did Pyroblast my own face once!
I meant we’re done with the round of changes and nerfs to old cards, right? So I can disenchant everything without worrying one will be changed and I could’ve got more dust from it.
For what it’s worth, if you dust something for the nerf value, you can just recraft it for the same dust if you decide you made a mistake. The downside is that you have to hold on to the dust, but if you open another knife juggler or FoN in the meantime, it means you save the full dust value rather than having to dust it for 25%
So yeah, shaman aggro is free wins right now. (Especially with the 7/7 overload 2 guy).
Among the notable cards that I pulled, I’m really happy with the Nzoth (re-summon all deathrattle minions) and the Shadowcaster (make a 1/1 (1) version of a minion).
I also pulled a Hallazeal (Shaman, heals for spell damage dealt), which looks pretty crap but I won’t dust it just yet.
Looks like it’s DR Rogue for me!
There’s too much power creep in these new cards. 3/4 3 drops and 4/5 4 drops with a big ability. Too many cards that have both great stats and a great effect.
I got my first legendary in 50 packs or so. Hogger. Wait, no, the new Hogger. Hogger, Doom of Elwynn. Is this the first time they’ve just made a second card of the same character? I guess he’d make a good fit for a self-damaging control warrior type (frothing berserker, armorsmith, etc).
I hope that’s not a waste of the legendary pity timer.
Woops, didn’t realize that was a theme. “Mukla, Tyrant of the Vale”, “Nat, The Darkfisher” - that seems all rather silly.
Yeah, there are a bunch of ‘corrupted’ versions of old cards in this set. And it is a bit silly.
I am looking forward to running into Rangaros, Lightlord 8 mana 8/8 that heals a random friendly for 8 at the end of your turn (apparently corruption is multiplicative). His line when healing is “LIVE, INSECT!”. 
I crafted a Yogg and plopped it in a reno mage shell. I did pyroblast my own face once, but with 7-8 spells, he does nothing more often than he does game winning/losing stuff.
Seems like he’s good only for clearing the board and filling your hand. I tried the Yogg simulator and he never seems to win the game on his own - just a reset of sorts, with the board state hopefully in your favour.
Tried C’thun Rogue yesterday. Managed to Blade of C’thun my opponent’s 15/15 C’thun and OTK him the turn after with my own 35/35 C’Thun.
Rank 13 Shenanigans 
Not a fan of the new expansion. C’Thun is ridonkulous. It would be understandable if it were a tougher buildup, but the minions to build him up are more powerful than just regular minions (hooded acoytle, twilight elder, etc), so there is no real reason, outside of not drawing him, for you to play another deck.
