Well yeah, not many people likes to play supporting class and i doubt there will be any supporting classes in Huxley.
In a video that i posted earlier in Huxley General:

You can see that after some time when he doesnt get hit, his armor starts to recharge, which works as selfhealing.
Plus on this screenshot:

You can see a player having skills called "Health Scan", not sure what it does but it's probably healing.
So all that idecates that there wont be much of supporting classes in Huxley, sorry for those who love it.
