After we just spent time defeating the entire Legion?
If the next expansion doesn't take it to 12 from the current 11 we are now, I frankly see no point going back to 9. The time for slow methodical filler expansions needs to die, hard. Fuck WoD, and fuck MoP too, even if it was a good filler expansion. Kinda contributed jack nothing to the overall story of the game save for origin stories and the tipsy time trio.
