I think it's better to qualify the fastest run, your line up need to be 1 tank 2 rogue 1 mage or 1 tank 1 rogue 2 mage.. So it would be fair for all classes and all classes have a chance to qualify leaderboards on their strategy, skills and items. and by NOT dummy using or free flagging and by not how long you played the game.

What do you think guys?
