To be honest, it's too little too late for me. It sounds good in theory, but the biggest issue remains the imbalance of the game, how it's become pay to win since nobody wants to post anything decent for in-game money.
This paragon level crap is just another grind to a dead game in my eyes. I know it's not literally dead, more of a figurative opinion - Blizzards marketing was good, Diablo 3 would die down right around the point where WoW's expansion would come along.
