I, and a few friends have noticed we are getting stun-locked a lot more recently and I have a suggested change.
Currently, most attacks stun you to some degree leaving you unable to attack or block for a brief time afterward.
This results in "stun-lock" which I have been noticing more and more as the game is updated with un-blockables and fancy mix-ups.
My suggestion: Reduce the recovery time for defence, leave the offensive recovery time the same.
I.E. Help eliminate stun-lock by allowing block sooner.
