Not quite sure if it's a bug or intended, but here goes.
I was dueling on the duel server, using a small mace against a guy with a greatsword. Obviously I wanted to get close to him to have a chance to attack and he, expecting this, started a kick (e kick ofc). And here is where it got weird. I managed to hit him, his character flinched and he lost damaged, BUT; the kick was still done, even though he was flinching, and hit me (since I was still moving closer to him) and I got stunned, it interrupted my secound attack, and he managed to do a counterattack because of the hit which was unblockable for me.
After that, I asked him over TS if he in fact was hit and it wasn't some weird lag thing. He confirmed he did get damaged and flinched. We then did some tests and we found out that even if you are hit by an attack, it doesn't interrupt the kick.
This might be intentional or it can be a bug. Regardless, it needs to be changed. If it's meant to be like this, please move this post to suggestions corner where I can argue about how ridiculous and unfair this is.
