Mea culpa. I read that as 2 damage procs: -resist, and +recharge. Yeah, I do consider 4 damage-oriented procs a proc'd out power.
Thanks for going to numbers. When surrounded by max enemies, the lowest rage I've seen was at 89%. I do not claim that this is definitive, but I think it's fair to assume that the balance for farming scenarios should be at 80 to 90. It's interesting that with the current (on beta) balance, Tankers will greatly underperform Brutes when in a perfect (for them) situation; this seems to run against the stated intent. This is of course looking only at direct power-based damage.
I reiterate that this discussion shows that the damage reductions are being made to bring down the highest possible damage in specialized situations without apparent regard for what that does for the rest of the game: the chaos of teams, the time spent leveling or soloing through missions to complete them instead of to maximize farming potential. In my opinion, overcap damage could do almost nothing other than keep attention for tanks, but then damage at say 50% and 100% of normal cap should be competitive with a brute at whatever fraction or multiplier the devs want.
I maybe was not clear about "enough" enemies. I am routinely surrounded by enough, as I pull as many as I can survive without leaving stragglers (if doing a defeat-all). I sincerely doubt they're all in my AOEs, except on the meteor map using specific enemies, and definitely not for most cones (probably throw spines is good, Jacob's Ladder is bad). But, I don't know that yet, I'll see if it's easily parsed.
