Honestly, like it matters. Stop balancing the game around people who play the game 15+ hours a day. Guess what, those players are going to leave just like they did before. In the end all Blizzard is doing is further pushing 'casuals' out of them game.
These nerfs are going to have far reaching complications post RoS. People think they merely nerfed some CotA mobs, that is not the case. The nerf to exp was across the board on well over half the monsters in the game. Wait around for a while. When the community buff is gone people are going to be singing a different tune.
In the end this is going to hurt the 'casual' player far more than the guy with 600 paragon levels prior to RoS release. Oh wait, are they going to revert the exp change on these monster types after RoS? Lol, no; but guess what? You are still going to be engaging those monsters when you run Rifts and Bounties.
Gonna report this run, sounds like it might be giving to much xp compared to the rest of the game.
