This has been there since season 2 began, shinobi, centurion, gladiator(much less frequent with highlander) all sometimes ignore the revenge activation of an enemy

I've noticed a lot that when shinobi strikes a revenge activation, it bounces of, like a light being blocked, he is not unbalanced most of the time, shinobi really could do with a small health buff btw (half a bar to get to 4)

Sometimes gladiators UB impale and toe stab both ignore activation and do damage + stagger

gladiator and cents punches against revenge activation still have stun properties, is that intended?

I've noticed these issues mostly with dlc characters, other times I could just say it was bad connection
