Gauntlet from Kinetic Melee triggering procs
Sounds like a "shush" moment to me.
Easy to see how it could arise when copy-pasting the powerset. Gauntlet AoE was disabled for a long time because of the issue of procs benefiting from the AoE (needlessly IMO, it's not as if tanks would have been OP).
I really should do something about this signature.
I recently made an Invuln/Kin tanker and I noticed, despite being solo, that some enemies I had not hit were being KBed or taking damage. I suspected that somehow my procs were being triggered from Gauntlet. I was using the GR pre-order enhancements which each have a 10% or 12% chance to do damage or KB. To further confirm this might not only be with them, I slotted an Explosive Strike: Chance for Smashing proc and got the same result.
I created and tested new tankers with the pre-order enhancements on all of melee power sets, but didn't see them doing the same.
Considering Kinetic Melee only has one AoE, this could alter the damage and crowd control it is capable of quite a bit I think.
