Current problems with machinist and being constructive.

Also add that we're a selfish dps without any tools to even help ourselves. No heal, no disengage, no movement speed increase, no shield, nothing.

Second wind, sheathe, sprint and peloton, tactician.

These things help themselves in the ways you described, but they aren't unique to Machinist, so your argument would be better if it said they don't have anything like repelling shot/en avant, warden's paean, battle voice/devilment, song party buffs, nature's minne, dance partner, curing waltz and improvisation.

It's hard to think of a lore reason why a Machinist would provide that sort of utility, but making Wildfire like Mug is a good idea.
