I think you were downrated because the way you worded your comment makes it sound like you think that just because you are geared you should never have to manage your resources. It is part of the game to manage resources, remember, this game stems from strategy game roots, everything in a strategy game is about resources. Granted WoW isn't a strategy game, it is an MMO and everything needs to be fun and balanced in a way that makes people want to continue playing and keeps them interested. If you have to keep an eye on your mana/etc then everything requires more thought, you can't just hit a button over and over again, you have to think about your moves carefully when mana runs low. I am sure that you don't think resources should be infinite because then you are just managing cooldowns and thats not fun at all. Resources are an integral part of the game and although you shouldn't have to watch them like a hawk when you are in a heroic in full tier 10, you should have to pay some sort of attention.
