Class balance? Or You are not playing your class right?
Most cry for a buff because they keep forgetting the positive side of the class they chose or they are playing it wrong and sorcs and warriors trying to be like rogue etc etc.
Some of my endgame and pvp level 13 friends remind and shows me of how a properly executed gameplay, attitude and class mastery has affected numerous scenario.
It really is a matter of how you choose to play your class. Mage trying to act like rog or warrior trying to be.. and rog to this or that.. will have a disastrous result and only causes frustration while it can be good sometimes but its like looking at a cupcake when it is near a premium grade cake.
