Just beat normal with my Wizard and beat the skeleton king on NM. I realize now why Wizard's have no issue on inferno, they are ridiculously OP. They have multiple stuns/knock back/distraction skills that can all be placed on the hotbar together with a 5 second skill that makes you INVINCIBLE that is on a 15 SECOND COOLDOWN, which is really only a 10 second cooldown as the cooldown starts as soon as you use it. Couple this with multiple AOE skills you can use at the same time with all the above, and a very solid, no mana costing single shot DPS, it's literally one of the most OP classes I have played in a game when comparing it against other classes in the game.
I just got done taking on 2 sets of champions (3 guys with fire chain and a champino/minions who lays down those laser beam things) at the same time and I literally got hit one single time, and that was because they were almost dead and I got careless. Obviously Hell/Inferno will be tougher, but on NM with my barb and with my friend's DH, it was challenging when you faced sets of champions, you got hit anyways and had to watch yourself, but this... man this is just straight out crazy OP.
Don't get me wrong, I'm having a blast with the Wizard but right now it's just not fair.
