They perform great with bars, but I rather give my rifles double bars, giving thompsons to airborne or invest ammo in the p47. It would be nice if they spawned out of buildings and remove weapon slots on them, because they get scoped rifles anyway.
While I would be open to making Paths more JLI-alike and making them better immediately while removing upgrading on them, I'm pretty just making them spawn out of buildings and removing their weapon slots would still make them pretty inferior to JLI (JLI's snipe execute is usually better and they have far more abilities).
