Well that's the perfect question, will allow me to develop my point.
For me, PvP is dead if there is no people to watch it on stream, no real competitions with real money involved.
The question is why are they so focused on balance when it's not the real problem, the actual game mode does not work in term of twitch views and "life" around the game, even if they balance it perfectly, there wont be a big living community around it because gamers don't like it (if they liked it, there would be a lot of streamers etc..).
