Not really interested in the lore. Blizzard has warned people off of the lore in their own way often enough. Gameplay over story yada yada yada.
I admire Chris's efforts to pull it together in the two recent books but as far as the game goes it's a tangled mess, self-contradictory and the game itself doesn't do even the smallest things to help.
As for faction war, I was over that a long time ago. It's the primary reason that I find myself not really very interested in BfA and may give it a pass. Which is likely to be sad because if I give the expansion a pass it's likely that I won't be returning any time soon.
