I like my wizard. With his tank gear on he can tank MP3 while a DH does most of the damage. I do not use a CM build either as I never had enough chance to crit. I also only had a dps of like 18K. I have spent maybe 1mil on that gear. A stormshield with reduced cost to meteor being most of that. With 1000+ LOH and 2-3% LS my health globe was always moving up down like a heart monitor. The real funny thing was how I could run into a huge back of mobs even elites and live, but once we got them down to 1-2 left I had to be really careful since there wasn't much left to still life from. I also noticed 1.05 made him much better at tanking mainly because frost nova lasts longer and health potions take into account +health from health globes now.
I just switched to a ray of frost dps build after spending about 600K on frostburn gauntlets and triumvirate. Switched because I don't know if anyone can tank at MP10. I did OK on MP3 solo, will try with my DH friend later. My dps is 29K now, but I have alot of plus %elmental damage that doesn't show up in that. I think I have 29% elemental + another 29% added to cold spells. Then I use about every skill the wizard has to add passive damage (thunderstorm, etc.) or +% damage (cold blood, slowtime w/ 20% rune, etc). I really wish the dps on your character was more meaningful. At best it is a guess and at worst leads you completely down the wrong path.
True neither build may fly through mobs like a barb with several million in gear, but I like him.
