Yeah, while i'm not a big gun-user in my fantasy games, I can appreciate being annoyed that your skills don't interact with your equipped weapon. As someone who plays primarily casters in mmos, I do get annoyed in, say, WoW when my mage just has their staff on their back while they're casting their spells.

Like, I know a part of the machinist fantasy is having a bunch of gadgets and doo-dahs to play around with but... If only there were types of machines that you could set up to act semi-autonomously and maintain while you're using your chosen signature weapon....
