I dont know much of the lore but there is mechanic/engineer at least as a crafting profession. I think it would be really cool to have like magic tech class using like an arm cannon and gadgets. But i think they could still be working on the current classes so I doubt this coupd be anytime soon. I just love the idea. Maybe it would have like ahots that require you to charge up for a larger blast or small ones for your main dps with throwable gadgets for support skills.
So like an Artificer?
I forgot D&D has that class. Yeah, something like that.
