Since this weapon has the option to have a chainsaw animation or be idle what if it worked with a meter like for the cleaners carbine or soda popper?

have some negetive downside like less base damage but once the meter is filled have it play a the moving chain animation and have it do higher damage through something like mini crits or some other effect.

Just saying that might work with this but stats like that may make it seem too close to the meter and critz of the phlog
