I think it's ri-damn-diculous how often I get caught up in moments where my opponent has me next to a ledge or in a corner and every time I actually manage to counter the guard break they can immediately pull off another one because not enough distance has been put between us (remember I can't move if I'm at the ledge or wall).
So essentially the fight turns into a mashing guard break fest where one lucky masher takes home the scrub award.
It's also insane just how unforgiving guard-breaks counters are... the timing windows is just too small. Listen up Ubisoft, my opponent can insta-kill me with a guard break. Make them easier to counter, I can be 0.001 seconds too late on a counter and there goes my entire life.
