How so?
PvP is an integral part of WoW. Even on pure PvE realms, people will still queue up for BGs if they want the ranked gear, which is quite good for PvE as well.
If they chose to balance the damage and healing numbers around interactions with other players, and then tuned raids in line with those values both sides of the fence are happy no?
PvE wouldn’t change at all if boss HP/Damage was nerfed as well to be in line with our lower damage and healing, and PvP wouldn’t be a crap show of one shots like we have now, or the healer meta we had in phase 1 due to the hidden damage reduction in WSG.
Hidden mechanics or blanket stam buffs are lazy band-aids to the root problem, which is lack of balanced numbers
