I dont think Legion is that bad, but its not the best for me. Best is still WOTLK for me, follow by BC. Legion is 3rd because of all the extra, but in term of Story telling, MoP is much better, I feel CATA and WoD story telling might even be alittle better, I'm just not feeling the story telling of Legion, Leveling in Legion is so Boring for me, but everything else is Good.
