First guild kill of Rotface the day he was released and he dropped Trauma. I believe it was a holy/disc priest that got it and he mentioned that he didn't see the proc going off. After some recount checking, it seemed to proc for 217 per second and he just didn't see it at all.
I did a little research just on wowhead and everyone seems to think it will benefit druids and paladin most, but be amazing for everyone. Now, I haven't done the math yet, but if you get roughly 2 procs per minute and every proc heals 4 people (it's limited by group) that's a HPS increase of 173.6. Now, that seems like a lot for just a proc, but in practice it's much lower.
From the recount data for 5 Putricide attempts in which he was healing the tank who was in the same group as melee, there were only 70 ticks from it. That's ~12 procs in roughly an hour. Granted, Putricide is not the best to test it on, but that was what were were on at the time.
Enough of my rambling, time for some answers! Is the proc on Trauma worth anything or should it be upgraded if something with better stats drops?
