When 1h stab got buffed I thought it was a good thing and I still dont mind the animation buff itself. I have to agree though that a lot of times I get 1h stabbed I think to myself "the hell ! this thing hit me before he even stabed". However, I have a feeling that the real problem is just EU1,EU2 being laggy as hell in the last weeks, as reported in the technical problems section a few times now.
This is the reason I usually played on EU4 because I can guarantee you, the performance is way better there. No matter what ping you have, and I have average 20, EU1,EU2 seems simply too laggy to register animations fast enough, and it is probably the same situation in NA. Same for ranged, sometimes hitboxes are half a meter in front of the playermodel, sometimes half a meter behind.
