I read project readme, checked client side and server side configurations, and no such feature exists - YES

Is your feature request related to a problem? Please describe.
As fun as BC is, it's made objectively worse than vanilla combat by the fact that you're stuck in the attack animation for so much longer, and therefor cannot block anywhere near as reactively.

Describe the solution you'd like
Ability to interupt the attack animation with right click to block instantly

Describe alternatives you've considered
adding some kind of stun to the attacks? but i think blocking is better
