I think of MoP as an illusion by a magician. "Look, over there ... PANDA!" (Please don't notice that this is actually a Troll expansion, OK? Yes, the Zandalari are back, and take the front for much of the expansion, but ... PANDA!)
I remember doing Kun-Lai Summit Quests, you're dealing with the Mogu.... Mogu..... Mogu.....
DA TROLLS BE HERE!
And I immediately rolled my eyes and went "......ugh, seriously, Blizzard? Really!?"
My fun and excitement were literally cut in half when the Zandalari popped in, I was like "ugh...... not AGAIN......"
Now we're in WoD and I'm just waiting to see how Blizz will make more Zandalari or somecrap and stick em in there... they'll find a way... they always do.
"DIDN'T YOU KNOW!? The Trolls were on Draenor too, and nobody knew!!"
That's about the time I cancel my sub.
