My dad actually mentioned this idea to me... How about power armor that follows you around when you're not in it? A lot like Titanfall, where when you get out it turns on an autopilot feature and you can order it to follow you around or stay put. Would be really awesome if it would actually help you fight as well. Now, I'm no mod creator so I have absolutely now idea how plausible the idea is, but I think would be a really cool option to the game, and it'd be pretty badass to see your tank of a power armor suit running around bashing people's skulls in while you chill out and eat some squirrel bits from behind cover.
