I've been playing around with it in search of main job to stick with. I don't find the job to be that difficult at all. For me, it's easier to play than Bard.
From how I understand how to play Machinist; Use Ricochet and Gauss Round on cooldown (Use Hypercharge/Heat Blast to reset them back to 2 stacks) Use Drill/Air Anchor on cool down (Use Reassemble with these whenever it's available) Use Wildfire, weapon skills increase the damage when you use them. I haven't reached max level to unlock Queen, but I assume you just cast Queen at 50 battery pack (Blue bar?) level same as the Auto-turret thingy? Then when you have nothing else to do, just use your normal 1-2-3 combo with Split Shot/Slug Shot/Clean Shot.
Seems straight forward. Was Machinist reworked or something? Or is the above completely wrong on how to play it?
