I had the thought in passing that the next engineer elite would be the Golemancer. Weapon : MaceThe made would focus in doing heavy single target damge hit,stun and confuse conditions. It's meant to represent a wrench whacking a person or a golem. The basic would be called percussive maintenance The toolbelt would be replaced with pet command skills/golem combat skills for you to be able to order around your golem when outside of it The utility skills would be like a minion Necro with a bunch of tiny mini golems focused for different utilities and damage And the Ult would be to get inside your golem and switch to a golem skillset I'd love the idea for either a personal questline or a gear set to customize the golem to the person's tastes but I don't think Anet would do that but I can dream. But that's just the rough sketch if my idea nothing big. If you guys think you can make it better or you think it's a poor idea and that they could do better let me know in the comments I'm 100% willing to discuss better ideas, improvements to this rough draft, and criticisms to the idea of golemancers whether due to lore or just simple dislike of the idea.
Fair play, I figured it could be a fun more lore intensive elite that would fit into the world nicely. It's however as you said kinda derivative so it's probably not what ANet has in mind.
