Cheers! Have fun in your new guild and progression. 
Cheers, SFG! Dreamwalker is cake, so it won’t be long. And I also agree that there should be a separate title for 10/25 Kingslayer, but guess you’ll just have to kill him on Heroic to separate yourself from the masses. 
I used to be more mercenary about progression, but after being in a top world guild in which I hated the leadership and made raiding into a 2nd job for me, I’ve since changed my outlook. Progression will come in time, especially with the attitude that Blizzard has taken towards progression, so I’m more concerned with genuinely enjoying the company of my guildmates more than progression. I could jump ship to a 12/12 Light of Dawn guild if I wanted, but I’d rather be there with people I actually like and care for a few weeks later.
