Do tanks need to lead the group, assing all tasks and essentially take responsibility for everything that happens? No, they do not. That attitude ist what kills tanks, good and bad. Anyone can lead, assign targets, whatever, does not even need to be the same person. Tasks can be shared within a group, you don't need to look at the tank like he is some kind of nanny. WoW tanks need to understand threat. They do not. Even if they played since the Dawn of Man, it is unlikely they understand what it means to not have a 500% threat boost. You can't switch targets willy-nilly and spread the love/hate. CC helps a lot, positioning is vital. Expecting tanks to manage that AND the rest of their own group is a little much, especially when they are not yet deep enough in their tanking tree. As an Assassin tank i can tell you the game changed a lot around mid 30s and AoE became almost trivial with wither (yeah i know, i'm bad for going deep darkness, i prefer 5% dmg reduce to convinience). Before that it was really annoying. And nothing you do matters if every dps chooses his own target. You cannot outthreat two people on different targets. It gets also really fun when the healer insists on getting guard while standing WAY outside its range. In conlusion: tanking is not hard, but different. You cannot expect tanks to perform like you do in a game that hands you so much in regards of threat and positioning. Also don't expect tanks to lead. If they don't, do it yourself. If you don't know enough about the groups skills to do that DO NOT EXPECT THE TANK TO KNOW! Ask. Work with what you learn. Lead the group to success. You don't want that responsiblity? Do not come here to moan that others don't want to do that either.
