PvP crit damage was off
Players of Classic PvP know exactly how things should feel, so it was clear from the start that something was off in WoW: Forever. Critical strikes did not seem to deal the proper amount of damage in PvP. Several Reddit threads pointed out the differences between Forever and Classic, one of them referencing a clip from the streamer Xaryu.
Following the community's concerns, Blizzard has now confirmed that this is not an intended change but a bug.
It is set to be fixed in a future build, after which critical strikes in PvP should behave as expected again.
