Perhaps I worded it a bit too blurry. I know the goal of stacking LOH is as a form of damage mitigation which buys you some time to kill the elites without kicking the bucket yourself, hence extending the window for yourself. And currently crit chance/crit damage is the way to go.

The reason for my post is that there only seems to be 2 ways to go for a more viable Inferno melee hero. Either by stacking sustain (Damage mitigation) or by health globe dependency for healing.

Edited : Help me theorize a potential build that can survive Inferno. Be creative! Screw cookie cutters.

Because in Inferno, Life Leech is cut to 20%. I wrote about it under 'sustain' in the initial post. For example to beat 2k LOH, assuming you get a massive 10% life leech :

DPS : 100k
Life Leech : 10%

Total life leeched from damage : 10k life

Inferno life leech rate (20%) : 10k * 20%

Total net life leech : 2k
As you can see, unless you're outputting massive amounts of damage consistently (Like over 100k DPS)...under current game mechanics LOH is more efficient.

It's for arguments sake that I used a nice round number to show efficiency between LOH and % life leech. It would be the same if I used numbers like 1476 LOH, but that would result in a little more work in calculation. In the end, it is just to highlight the difference in efficiency.
