here is a patch note from Facebook for changes to PVP DAMAGE ONLY [Patch note - V2.81] Character skill balance for PVP | Facebook
there are also changes to stage damage in a separate patch note, but we have seen them change stage damage so much in the past that all the news seem to blend together into an "oh this again"
anyway i have separated the PVP patch notes into little spoiler windows for organization:
looks like sieg, krieg, ryan and ralph got the biggest nerfs.
please note that sieg's pvp nerf
could be AFTER the initial stage buff
, meaning the nerf isn't as big a nerf as it seems
