Okay? And then everyone who isn't have fun will leave and go do something they find fun, and everyone left will be people who enjoy it. I don't really see how that's a problem, nobody is forcing you to play a game you don't enjoy.
You keep talking about things not being "fun", what you don't seem to grasp is that what you find fun and what others find fun are not always the same thing. You're looking for a competitive PvP game yet you're playing something that is fundamentally not competitive. If you go into it with the mindset of just chilling and having a good time it's fun regardless of balance.
As I already mentioned, playing my 474 ilvl DH with Twilight Dev 8 was hilariously fun in arena. You know what isn't fun in arena? Playing against old LSD comps that dragged every game out for 15 minutes by hiding behind pillars. Was the game more balanced then? Sure. Was it more fun? Hell no. You know what's not fun? Playing against Lock/Mage/Paladin where nothing can ever die and if they get one cast off you lose. But you know what is fun? Proc'ing 2 tentacles in a Kidney Shot on my Rogue and watching someone die from 90% while being unable to fight back, that's super fun.
