He is saying that with Sabrewulf when doing this combo: Light ragged edge (opener), cr HK (manual) and adding a light ragged edge linker he is getting instead the running upercut ender when playing from the right (Player 2 side). He’s not getting it that often or nearly never when playing from the left side.
I think it’s an execution issue tbh. I haven’t find a bug while testing it. My guess is an input issue happening between the cr.HK manual and the light ragged edge command.
Some ppl have trouble performing dps from different sides, so it can be quite normal.
