The issue you're going to run into is PC AC versus mobs with incredibly high ATK. I'm actually arguing that AC doesn't make a lethal scenario come up that much less in the scenarios where you actually want gear. The shit you actually want some gear for in Velious is going to have really fuckin' high ATK.

Take a look at the AoW logs from beta:

You have tanks who are presumably already at the softcap for AC getting smashed. Looking at the short logs, the DI (when you account for defensive) curve appears centered ~18-19ish. If your non-defensive DI curve is centered around a DI of 18 with AC stacking vs a DI of 19 with HP stacking, it means fuck all if you're mitigating a bit better if you still have a large chance of being one-rounded.

I always see these ac threads and think cool maybe ill learn something new this time... I guess this is just another ac thread though = \

This is good enough information for me.

Pasi, you're going way over my head. I'm gonna need someone to explain this to me like I'm 5 years old.

Don't let haynar haynar you zander, you're better than that

You guys are both generally correct. But vs high atk mobs, Pasi is slightly more correct.

ATK is not what is important; it's the number of attacks.

Both are determining factors. But you're right, the more a mob attacks the more likely it is that central limit theorem applies. However, if you can get your hp total greater than the damage a mob can do in x rounds, it's going to be the superior choice. Imagine an extreme example of +10,000 ac or +10,000 hp. With complete heal, the HP will guarantee your tank doesn't die, but the ac allows for the possibility.

If you can't live through a max round, AC may/will be the better choice, depending on the mobs mean DI, number of hits per round, etc. There's an equation we could plug in to determine the probability exactly. There's 2 intersecting lines where one or the other is the superior choice. So it's definitely not a certainty either way (unless you can live through a max round with more hp, but couldn't with more ac)

I mean, I just did this earlier in the thread, although it was a simulation and not a closed form equation.

Obviously it will look different for every mob of course, and I have no idea how the Spiroc Lord is tuned vs Velious mobs
