teletype is mostly right. A few clarifictions and my own thoughts follow:
#1: Yeah, it’s a lot of fun. Especially if you’re into Lord of the Rings.
#2: teletype is pretty much spot on here. To expand on it a little though - the game is EXTREMELY solo friendly. You can go 1-65 with any class, easily, no question. (Well, 1-50 if you don’t want to pay.) You won’t have “the best stuff” but you’ll do just fine. There are many places in the game where obsessive compulsive people will get stuck and try to grind, however, but that is because these people have a personality disorder, not because the game is forcing you. For example, all zones in the game have associated Deeds. Deeds are sortof like quests or accomplishments, and they give small rewards for completion - usually a title, or a point in a virtue. Virtues are ‘traits’ you can equip that give small stat bonuses to your characters. Some of the deeds in some of the zones are along the lines of “Defeat Wargs in Angmar (150)” for a title and then “Defeat Wargs in Angmar(300)” for a point of a Virtue. A sane man would not grind 300 Wargs in Angmar for 3 points of agility and 8 points of morale (The net effect of an extra point in that virtue, assuming you’re even using it.). An obsessive compulsive person might. Don’t be obsessive compulsive.
#3: The easiest classes to get groups as are the ones that have clearly defined roles that every group needs: Healers and Tanks. Healers means Minstrels, Runekeepers, and sometimes Captains, Tanks means Guardians, Wardens, and sometimes Champions (and very very sometimes Captains.) These are the classes which, if they are absent, will put the brakes on a group. (Which is not to say you can’t do group instances without these classes, but it will depend on the players and the instance.)
#4: There’s a chart HERE that identifies what you get and don’t get for free play vs “have recently bought stuff” vs having a subscription. However, it’s a bit confusing because it’s not clear what a lot of the stuff means (I still don’t know what ‘quest packs’ are. -_- ). Basically though, you’ll be restricted in some way in most aspects of the game. Generally, things will still be available to you, but you’ll get less of them. (Fewer character slots, inventory slots, lower level cap, lower crafting tiers, can buy but not sell in auction house, fewer trait slots, etc, etc.) The real big limiter is, as mentioned, that you won’t have access to areas outside the “original” LotRO: Shadows of Angmar areas. No Moria, no Lorien, no Mirkwood, no Enedwaith. Still, that’s a LOT of game, and many of the restrictions relax (for a while, anyway. Not entirely sure how this is handled) if you buy pretty much any Turbine points.
Certainly, you have nothing to lose except the very large download by giving it a shot. If you decide to join Windfola or Arkenstone, post your character name(s) here and I’ll drop you a line in game sometime!
