For all of the flack that people have given MoP, I have to wonder if they were seriously raiding during that period or just faffing about, doing LFR, and nothing else?
The world was beautiful and while there were WAY too many dailies at the start of the expansion, the exploration aspects and some of the things they implemented ('Treasures', more rares, etc.) were quite fun and will be a larger part of the WoD game cycle.
The raids themselves ranged from 'eh' (Mogu) to great (ToT) to awesome (SoO - It would be amongst the better tiers if only 1) It had not gone on for 14 months due to poor planning, 2) Some of the later heroic fights were not so ball-crushingly tuned).
