Why does the general WoW player base hate PvP?

Overwatch never once clicked for me as a PvP game.
But I had already been a career tf2 player for years and wasn’t really willing to reprogram myself.

Also Overwatch has a lot of focus on Tracking aim, and also lots of characters that don’t focus on aim at all. Like Mei or Symettra. Which felt out of place in a shooter.

No smoke towards people who do enjoy overwatch. But my enjoyment was limited to like Phara and Ana.
