I agree pretty much all around, just the only part I'd be concerned about would be Nkuch-ing (body w/sniper, clean w/primary). Maybe if it's possible, they could have an invisible timer similar to how assists work that would prevent Scavs from working even if they got a primary kill? Plus, for Trials at least, I personally think that 2 special on getting revived is a bit ridiculous, same applies for getting special from your own dead teammates.
