Added worgen and goblins, had firelands raid, added transmog.
7/10 at worst.
Toss up between WoD and SL for actual worse, wod had good content til they abandoned it for a year and a half to rot.
SL was just so bad til the final patch; usually an expansion gets its fixes ~halfway through, the core of SL still felt like a grindy, souless, feedback ignoring mess right until zovaal died.
