How many people use all the classes?

This is me.
I play Assault, Medic and Support.
I’m finding that I don’t play Medic as much as I used to. The weapons seem to be outclassed by everything else.
I find Support and Assualt really fun.
This wasn’t part of your question, but I hardly every pilot or tanker outright, though I might hitch a ride from time to time.
