Even Rhykker (ultimate Diablo fan boy) is admitting Diablo 4's shortcomings?

I’ve seen people say this a lot… do players actually think D4 development started before D3: RoS was even released? Has someone from Blizzard ever said D4 development started that far back, and I just missed it?

I’ve always figured D4 development didn’t start until the Necromancer release on D3. It always felt like the Necro was the abandoned 2nd expansion for D3, and it was abandoned to start development on D4.
