Midas touch exotic talent - Landing shots gives team armor buff for 10 seconds.
Or
Kills refill current clip of your team
Or
Target gets blinded
Something has to be better than debuffing yourself and your target. I really don't know as I'm on console and don't have access to the PTS.
But from the sounds of it it sounds like it'll remained unused as is.
First one would make Hunter's faith set to garbage.....(....anyway it's garbage though)
Second one would be OK if your team uses shotgun or LMG, but need to exclude yourself.
Third one, we have Toxic talent already!
Since TD is cover based shooter, enemy damage reduction debuff seems not attractive.
I would prefer some kind of temporary team RPM buff, while my rpm goes down.
HF is already useless though as you lose armor when a bullet hits you. At least with my perk the armor buff is on a timer.
