Autosuggestion much?
Hardly. Since I didn't see anyone else in the thread mentioning the strange chamber animation (until now) I assumed it was the swing itself which was slower.
Anyway, I don't think it's the slower swings which are causing so much butthurt right now, rather the way in which it was implemented. The 2H right swing really seems odd now, and it messes with your rhythm when you're fighting for your life. For comparison, I played with a polearm alt last night and the swing
felt the same as always, which is an important point. Changing the way combat feels makes the change more noticeable and harder to deal with.
