I actually sometimes question if Blizz even reads the answers when people unsub, since you'd think by now they'd have figured out ways to keep players from leaving in droves every other quarter.
But, since this seems like it will inevitably set the tone for 7.0 (since that seems like their next big update after 6.2), it's probably a good idea to poll the WoW-quitters on MMO-Champion for why they left the game. They always have some kind of big about-face in new expansions to try and stem the bleeding from last expansion, and maybe we can get a better idea of not just the lore but the content of 7.0 if we know why people quit in 6.1.

EDIT: Thanks to the mod who unlocked this after it got caught up in the blanket "lock everything about the sub numbers."
EDIT 2: I get a lot of you want to respond with "No Flying" in the poll, but I actually kept that out on purpose. Yes a lot of people are mad about it, but a lot of those people are mad about "No Flying and..." I'd rather get ideas besides just 1000 "add flying back in" ideas since there's more wrong than just that.
