EDIT:

I was thinking about what EHP really means as I was debating on whether an Inna’s Temperance would be better with 50+ resists or 150+ vitality.

Logic tells me the 150 vit is a better choice. According to various EHP calculators if I got 150 vit, that would be ~84k EHP versus ~34k ehp (50AR) to 55K EHP (80AR).

This really looks like a no brainer. Really, it does. I want more EHP, right?

I would argue this is wrong, and the reason for this comes in the forms of sustain, most notably, (and the one I use) life steal.

Lifesteal heals a % of the damage you deal(I think like less than 1% in inferno, but for the sake of my point we will just use 1%). Since we can’t accurately calculate lifesteal based on sheet dps, we have to use effective dps, but in this case, I’m just going to use one wave of light worth of damage.

My WOL has been critting for 600k lately, so we will use that number. According to my possibly made up 1% lifesteal amount, I should get a whopping 6,000 hp if I crit one mob. Let’s say that I’m a badass and I crit 3 out of 3 mobs for exactly 600k each. Sweet. I just got back 18,000 hp, which is good because I’m standing in a desecrate.

What effect does EHP have on this? Well, that 18,000 is healed from my max health pool, not my EHP, so 18k is 18k is 18k. The game doesn’t care if I’m naked and have only 18k hp and no armor or resists. It also doesn’t care if I have 1,000 resists and 10,000 armor. See where I’m going with this?

I think there is a danger to getting too much vitality at the expense of having less resists just so you can flaunt your 75k health pool around.

Let’s do some math. I’m not actually going to calculate everything like the game does, but am just going to use made up examples to prove a point.

Let’s say 100k hp with 400 all resists and 4,000 armor gives me a sweet 1,000,000 EHP. Let’s also say my friend has 800 all resist and 8k hp, but only 40k hp, but his EHP is also 1,000,000. I call him a noob cus his health is so low, amirite?

But, what happens in this situation is that when we both crit 3 mobs for 600k and get 18k health back, he gets WAY more effective health back, making his sustain almost twice as powerful. How much EHP do we get for 18k hp?

1,000,000/100,000= for every 1 hit point I have 10 EHP. So 18k gives me 180,000k EHP.

1,000,000/40,000= for every 1 hit point my friend has 25 EHP and gets 450,000 EHP from that same WOL. Almost half his effective health. Talk about some overhealing.

So if we lose effective health at the same exact rate, his sustain is always going to come out on top if he has more resists and armor and less vitality. (Don’t get me wrong, if he has 800/8000 and can maintain those with MORE vitality he should, but dropping below those, in my example, for more vit would be counterproductive)

I personally feel like I’ve dropped too many resistances at the expense of more vitality and it’s weakened my monk.

Also, if my theoretical math is fundamentally wrong, let me know.

So my question is this: Where is the breakpoint between too few resists and too much hp to adequately sustain?

tl;dr: I’m just pondering. Ponder with me, or don’t.

I have since discovered the beautiful importance of the HP:EHP ratio. You only need a high EHP pool to withstand burst damage. If you can get to a comfortable max EHP pool size you should focus only on ratio, and keeping the pool size the same. This makes your sustain more effective. I went from 1:12 to 1:17 and saw a HUGE increase in how awesome I am, both in game and IRL ;)

Just a quick example that illustrates my point(with quite an exaggeration). Lets say 2 people have 500,000 ehp:

Person 1 has 100k hp, so a ratio of 1:5

Person 2 has 20k hp, so a ratio of 1:25

They both take a potion, healing them for 10k hp.

Person 1 recieves 10k*5=50,000 EHP heal from the potion

Person 2 recieves 10k*25=250,000 EHP heal from the potion

Person 1 has just restored 1/10 of his ehp and person 2 has restored 1/2 of his EHP. Even though they have the same EHP pool, person 2 has an enormous advantage in outhealing incoming damage through lifesteal, life on hit, health globes, potions, regen etc.

For my own example. A 10k heal at 1:12 vs. 1:17 is a difference of 120,000 heal versus 170,000 heal. That doesn't seem like much, but when you're churning out tons of LS heals, a 30% boost is huge.
