What an interesting take, I’m sorry if you’ve had a bad experience with PvP but thankfully they introduced Warmode and you don’t need to participate. Personally I don’t care for Pet Battles or Mythic+ really, but I think the World is a richer place with them in it and would never scoff at people who enjoy that content.
We pay the same price as everyone else who plays wow and at $15/month it isn’t really cheap and even in more popular content like Raiding and Mythic+ Blizzard dedicates the bare minimum. With all the money Blizzard has saved over the years doing next to nothing for PvP they can certainly afford to fix some not even all the issues plaguing it, especially if they’re going to consider it an E-Sport and an Endgame Pillar.
I’d recommend checking out this post I made
Particularly the tab close to the bottom titled something like - Address Why Players Left to Begin With.
You’ll come to learn that PvP was actually very popular early on and it wasn’t until it was neglected that players decided to leave. The issue wasn’t people don’t like it so lets not fund it, it was lets not fund it, now people don’t like it.
