Then you must make Diablo IV way much better than Diablo 3. Make it greater! Also, listen to previous Diablo fans. Stop ignore them, or we all lose faith in Blizzard.
You got two options:
1.) Make your game however you want it, it’s a 50% chance we all would hate it or love it. But it’s a scary risk to take.
2.) Listen to their fans. = WinWin
We all just want an epic Diablo game, that everybody loves!
Not another Diablo 3 clone game.
