Although I did not try MoP heroic 5 mans on release because I had no interest on buying MoP to being with, this is the same argument I read about WotLK and Cataclysm heroic. It was wrong for both expansions: WotLK and Cataclysm heroics were absolutely trivial compared to BC heroics, at any level of comparable gear. So are you telling me that they erased WotLK and Cataclysm design and went back to BC model of heroics for MoP? Because, from the little I saw by tanking late MoP heroics with pre-raid gear and not-so-good groups, I believe your saying huge bullshit.
Wow, should we be impressed?
