That is what gets me. Each class has a roll. If you stay with-in your roll things will go nicely. The reason I pick on pallies is because they think they are warriors and as you both rightly pointed out they are not. I don't pretend my battleshout can buff the raid.
Everytime I get in a raid with a new 60 pally there is always trouble. He comes in with his green geared arss and talks smack while he pulls. I usually end up booting them out of the raid. This is a mentality that only pallies have because of their ability to wear plate.
What I hate it dueling pallies. I can't kick their ass with 6 swings while they are doing almost nothing to me. Then they put up that stupid shield and heal them selves full. As a result I don't duel them.
