My initial reaction to this was that defining the right way to play completely contradicted the spirit of the post in all of its (self-proclaimed) Satirical, ironic, sarcastic glory. but wanting to keep the 666 post count up there for a while gave me time to think and I guess I am willing to attempt it after all here goes:
“Right Way to Play Diablo IV” - Any way that gives you what you want from the game that is possible in the confines of the game mechanics and does not violate the TOS
I think a lack of immediate responses from me may be just what this thread needed 
I hope people get some amusement from this, and maybe even some food for thought about how we approach the game and our fellow demon slayers!
