Thing is, magic missile sucks? In what situation will you prefer casting a magic missile to casting an arcane orb??? I dont see the point :s. Unless you get starved for arcane I guess, which tbh is easy to avoid.

Guess Ill have to find me a decent weapon to try life leech out :).

Mind elaborating your spec/strat for inferno runs?

And what LoH numbers do you normally get with a 50k dps gear?

Just to clarify, Life Leech and LoH are not the same thing.
Life Leech just plain sucks, period.

For more information on LoH for Wizards, check out this thread:

I prefer life regen. But meh.
Prolly 'cuz I'm poor.

Life on hit is reliable, but sorta sucky for after the battle. Life steal is great if you are critting for over 200k consistantly. If not, don't bother.

Life regen is lovely, but I believe it only gives you half the amount you equip. For example, when I equip 1000 life regen, it regens 500. I'm not sure if that's because I'm in inferno, or the regen text comes up twice per second, or some other reason.

It's listed as "1000 Health Points Regenerated Per Second" but the actual ticks do not happen every second. I don't think it's 50% over 2 ticks, either.

If that's the case, that's good then. I thought it was an inferno thing, like Life Steal.

But yeah, life regen is really helpful after a fight when you don't have much HP left. Without it, you either gotta wait for that pot cooldown, or hope your life on hit regens enough HP before the next hit.
