I disagree, Heavy slow weapons, like UGS needs a defense against faster weapons, and that is the parry. Maybe hornet is too stronk, but also is a goodamn Goddard Twinswords that can take of you like 1/3 HP with a fucking roll into L1, with buffs and leo's ring and then you are like «why I have an UGS at all when I can have that at much less weight, faster, less stamina consumption and deceiving long reach» and the answer is «because If I can get a parry or a hit on that fucker he's done».
Parry are easy to punish, parries are unreliable and they aren't that useful against a smart player, but also is a deterrent for shitty spamming tactics and battle arts.
Maybe it shouldn't be a one hit kill, but the whole point of heavy weapons is hitting hard, so if get a parry on a stupid dork sword user I expect that he's gonna receive a lot of damage.
The problem is that when you make hornet ring less effective, that applies to daggers too.
Daggers are already hard to use. Make them do more damage than an UGS on a hornet ring repost and now you have a good reason to use them.
I should wait to see the critical damage increase for daggers before saying anything but I doubt it will be that big.
UGS do already a lot of damage and giving them the advantage with riposts/backstabs (which are originally made for assassins) over daggers doesn't make sense to me.
