Current problems with machinist and being constructive.

[Donoman]

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.

I'm obviously talking about things outside of the base kit that is available to everyone... But sure I'll edit that to specify. I'm also not talking about group utility, I'm talking about something like Mana Ward, En Avant, Aetherial Maniuplation etc... selfish utility that just makes life easier when dealing with mechanics / screw ups.
