This doesn't sound right. These 2 weapons weren't designed to be a combo so, honestly, it shouldn't be a combo. I think meds stopping it, whether it's intentional or not, is a good thing. Maneuvering against hale should be a skill, not a "I hurt myself, do small but accurate (and therefore consistent) damage to refill my boost, now I go vroom vroom quick, come get me Hale". To me, that just sounds like it's either going to stall the round by either chipping at Hale extremely slowly or the Scout just outrunning him.
I don't play Hale so I don't know the analytics behind it but hypothetically, it doesn't sound fun for Hale or for people waiting for the round to end.
