I don’t think most of these don’t even need reduce bonus tbh. Limb Splitter 10-25% power on first attack is really not too OP or anything. Even Decimator can give up to 20-50% power just from chaining your attack.
Either they make the downside/condition gone, or make the upside give a lot more bonus to be worth it. I kinda prefer the latter since it also affect how player use their weapon too.
I would say blessing that grant more power just from killing enemies is pretty no brainer, I mean what the hell are you suppose to do with your weapon anyway if not use it to kill enemy? lol
