After a few hours trying the mechanist, IMO, the golem pet thing it's a mess. i would prefer a summon system like the guardians spirits weapon, where you cast a specific golem tie to the mastery trait, and in a similar way, a golem ports in, do the skill, and then fly away/explode/idk.
Mace also feels weird and slow, like even more slow than the scrapper hammer, and the confusion it's kinda bad.
Just my 2 cents for future conversations....
