Great video. I felt smarter just listening to it.

As you can see between 600ac and 800ac there is a noticeable improvement in mitigation. However, after 800ac it's a marginal difference. When tanking raid targets, there is little to no difference between 800ac and 1,000ac. Also consider the random number generator factor. In my opinion on P99 currently - HP still reigns supreme especially when engaging raid targets. Use this data for whatever you'd like.

Your sample size is sufficient to establish a pretty strong confidence interval. AC clearly caps off at some point. From what I recall of dev postings, there was indeed a hardcap on worn AC, but I feel like it's much lower here than it was on live. In retrospect, I'm sure that's why the devs put 40-50+ ac on items in Velious, because it wouldn't make as big of a difference as players expected it would.

One thing that would be beneficial to establish is how the AC equation works. Is there a difference in ac from defense, buffs, or gear. Does certain AC cap at a point? Is there a class cap? Etc.
