I know all the ways a mage can deal damage to you. If you are tardy enough to not get out of the root or use something like a spell reflect, a mage will deep you. Otherwise the only way a mage can deep freeze you is with frozen orb and pet freeze. If you can break free from that deep freeze somehow.. There is almost nothing a mage will be able to do. Pom + Ring is the only really effective control left after deep. A mage can't just jump and kite and kill you. Without casting there are two things a mage can gain fingers of frost from. One is pet freeze which only gives the mage one proc, the other is frozen orb which wil most likely give the mage one proc as well. If you are good enough to break your roots, the mage will have to use one of those procs to deep you. Everything a mage can do is so predictable and almost everything a mage can do is counterable somehow.
I agree that mages are in top 5. With the damage and control they can put out, they will almost always be good. They have very good survivability added tot his. But they are not broken enough to make some classes useless in arena, they are not the class that people should be QQing about anymore(they are definitely not godly as they were in duels.) The QQ is never ending because some people just prefer being baddies instead of learning the game.
