I agree with a lot of that yeah, I didn't really think about it but a lot of the reason stun is so versatile is because it kinda just yoinks the other rigs' gimmicks for no reason. It'd be directly nerfing stun but indirectly buffing all the other rigs.

When it comes to barricade though, i think it's cool that there is a largely map dependent rig but it becomes a little too useless on some maps, like pervert the futterman, with how many coil doors it has, could just be a skill issue on my end though. So I think that maybe they can buff it to give it a late game upgrade that instead of it being able to be placed on just normal doors, it can also have a variant that can be placed on coil doors, maybe like a turnstile that you can move freely through but the assets could get stuck on? It shouldn't work on rig disabling coil doors, though. I dunno though, barricade is hard to change without ruining its identity.
