The drawback is that Europeans use animation breaks, too. So it isn't just a matter of learning animations, it becomes only a guessing game.Yeah lets nerf anything that can get through parries. We cant have players mis parrying right, even if they can correct their block direction in a fraction of a second.
Actually having to duel for a few hours and learn the animations? Nah thats too much work...
Btw they cost more stam to swing and are slower than swords, while costing double the skill points. Why would anyone bother if they drained even more?
