No off-hand hit cooldown

Hello, this is my first time using Github so I hope this is the correct way to ask.
Is there a solution to the off-hand attacks being so rapid? there is no cooldown between hits on the off-hand, making it OP unlike the primary hand which has a wait time in-between hits. This issue allows me to quickly knockback and kill enemies. People said download Better Hurt Timer but all that does is make your primary hand the same way as your off-hand, OP. this mod is perfect but that is literally the only issue. Thank you :)

oh, are you using mixinbooter or mixinbootstrap?

No I am not, first time I heard of those mods. I don't have any other mods installed that affect the hands or provide any other slots. I've also seen that in the forge comments, other people have the same issue
