Not to burst your bubble, but with approximately 500K EHP, you're not in all that better shape than most people gearing for EHP. I have a wizard friend that runs about 300K unbuffed DPS with nearly 1 million unbuffed EHP. Based on DiabloProgress, stats-wise he can kill me off if I go head-to-head with him.
Also, there is no PvP right now, so any speculation for what build/stats to run is pretty moot right now. The only skill anyone can agree with for wizard in PvP is Seeker Missile, that's about it.
