Lol, nice. But calculations are pretty far off from what I'm seeing, and I'm not sure how you're getting them.
Valk's damage formula, which has been pretty good at estimating IB damage (e.g. Kunkka v. Faction), predicts 1.3756 crit-adjusted damage per potency. This is 1650.72 healed from IB after Maim and Storm's Eye. At 4 uses per minute (1 per 20s plus Infuriate), that's about 110 health per second excluding other cooldowns. If you get 2 of them off in Berserk per 90s, you'd be at less than 125 per second average (assuming 40% net damage boost from Berserk). Second Wind heals half as much as Inner Beast at 120-second intervals; it should be about 6.875 HP per second in over time. Thus, you're invariably less than 132 HP/s. That is the absolute limit, and thoroughly impractical. It also ignores overheal. Furthermore, if you look at the simplest no-off-GCD rotation, the average number of Wrath stacks is 2.33, or a 7% healing boost. If you compare to off-GCD rotations, you will vary between 6.0% (drop ability immediately before IB, which is exactly what you'll be doing with Berserk) and 7.7% (drop ability immediately after IB, thoroughly impractical). No matter how you slice it, Wrath's average bonus should be around 7% for a maximum-IB-spam setup. Now, that mitigation amount is tied to enemy damage input; you are healed as much as you are damaged. You adjust for amount recovered by self-healing, then divide by healing bonus according to this effective formula:
Wrath healing load relieved = [1 - 1/(1 + Wrathbonus)] * [damage taken rate - (self-healing rate * overheal ratio)]
Thus, at 1000 incoming DPS and 7% average Wrath bonus, you recover an effective 56.8 HP per second additional. This comes out to a total of around 188 mitigation per second at absolute max. Comparatively, if PLD is blocking 5% more incoming damage compared to WAR (which cannot block at all), then you expect a best-case comparison to be 240 passively mitigated by PLD compared to 188 actively mitigated by WAR. Just sitting on Wrath stacks gives you 130/s, which speaks about as ill of WAR's self-healing as could be imagined. If you want to include Rampart, Sentinel and Hallowed Ground as a rate, then PLD would be effectively just under 315 per second at 1000 incoming DPS. PLD
will get all of that, of course, but if you want to look at what a WAR will realistically get, you can pretty much shave 20% off the top due to overheals and imperfect use. In any realistic endgame scenario, PLD will mitigate twice as much as WAR or more, plus superior burst reserve.
//EDIT: I realized that I forgot Inner Release and Thrill of Battle. IR will increase average self-healing rate by less than 1 per second (0.835). ToB at 6300 HP will give you 1260 back, or 10.5 per second when time-weighted. Still less than 200 in the very best case.
