WoW's biggest problem is the vocal minority. I, for one, am glad they don't take all our ideas (even mine) on what might make the game "better"' and implement them. It's funny, because some of these ideas and suggestions were removed or added previously because players didn't like the state the game was in with or without them. And now we bitch about the decisions to reverse previous decisions, and so on, and so on. Heroics are too easy, heroics are too difficult, heroics are too easy. Good grief.
I do wish, however, that premade groups were more rewarding, and believe that heroic scenarios were a step in the right direction. So we've got solo, three player, five player, 10 and 25 instances. Would like to see something for a 7 or 8-man grouping next.
