How about increasing the range of the syringe gun slightly, to something like 2 meters to compensate the bunnyhopping, bouncing and leaping players they have to heal. Or give them a healing dart pistol?
I think flashbangs would be quite an useful tool too, if they stunned the enemy for a couple of seconds. I would have so many uses for these. Of course, I think Siren and Patriarch would have to be immune to it, and the effect should have a greatly shortened duration on things like FP and Scrake, as a downside this would enrage the FP and Scrake as soon as it wears off. Replace grenades with Flashbangs and limit their number to 2 or 3.
