KK, will show if its not sold. :-)
For Life Steal %, in inferno they have nerf it. So not effective already. For other difficulties it works 100% as per the stats shown.

In inferno i think they nerf it to 0.2% for the full 100% stats.

LoH would be a much better option.

Its rather unfair to Monk, as if you use WotF, even though you hit 7 hits ( without rune ), you only get 1 time LOH as its consider as one attack with multiple hits.

Barb with WotB hit so damn fast, and crit dmg n chance passive, and with overpower n ignore pain, so imba.

works like this:

if the damage you deal = 100k
3% life steal = 3k life back to you

but since inferno nerf that to 20%, you only get 3k * 20% = 600 life.

that is almost the same as if you have a LoH of 600.

except, LoH has co-efficiency on multiple target. meaning to say, when you use skill such as FoT (that hit multiple targets), you only get 75% of 600 LoH. but it's for every target.

Life steal does not have co-efficiency, so, you will get pure 600 on each target.

range got nothing to do with this.

If you got 100k damage deal. Most of our monk deal how much damage? My dps is just 16k with 200% critical hit is only 30k maybe? Life steal nerfed so you get 200 life back.
LoH 600 is always 600 whether you hit a target dealing 3k damage or 30k damage. So  LoH wins.

Best? LoH + fast or High Crit chance + High crit dmg (as per Sifu's advise)

above 15% crit chance id say cyclone.

7ss is nice

and yes MF/GF is capped at 300% excluding 5NV stack (so +5 nephalem = 375%)
