I’d probably re-sub to the game for 6 months or so if they took all flight requirements out of the old expansions.
If they actually added flight to the permanent no-fly zones of the past at the same time, I would probably stay subbed permanently (but one expansion behind). I realize that would never happen though, because Bliz would not want to pay for it and they seem to despise flight... but I’m throwing it out there.
At the very least, I hope they remove the restriction on BfA when the next expansion comes out... if so, I might come back for a short stretch and do that expansion.
Anyway, how do you feel about it?
