I’ve never gotten into WoW PvP just because I could instantly discern the community at large is exploit early exploit often happy and loves to pay to win. It’s not limited to boosting for keys or raids, but people will win trade and cheat PvP in general in blizzard games.
It’s why I quit overwatch when it was still 1.0 - blizzard doesn’t care about the integrity of the game, only appearances.
