Then, all of a sudden, you are supposed to be grouping with your friends for the content! Huh? What friends? When are people supposed to have developed those sorts of relationships along the way? Why would they?
And find dedicated 12 man teams for timed content? Don't make me laugh. Sure, a few guilds will have the foresight to have put that sort of community together, but very few.
Load gun.
Aim at foot.
Pull trigger.
