Quick question about healing scrapper

[Calen.8945]

Before the scrapper drama, I was playing around with quickness/dps role instead of a pure dps. However, lately I've been playing around with Med kit and my god this kit is so fun to use. To the point that I grabbed zealot gear so I could use it better. That said, in fractals I've found I have to play the quickness, dps, and heal role at the same time.

 

I'm using Inventions and Alchemy traits at the moment. So, if I remove Alchemy for Explosives would that hurt my healing too bad. And would cutting out the quickness spam to focus on healing/dps be bad for a supportish build?
