indeed i am, here are the stats on my humpback build:
machinist is overally not worth it, only 5000 more health than the humpback one, even at maximum optimization, and the 25% more weapon durability is not worth it, at all, you will do worse than if you were using any other cabin, even epics, simply, by the time you will lose your weapon, or get destroyed due to cabin damage, you could have been able to destroy various different enemys if you were using a different cabin.
