Why can't we at least comment Community Council posts? This problem affects me too. My situation: I have only one favorite ground mount and large collection of favorite flying mounts. I don't want my flying mounts to be summoned in no flying locations - only my ground mount. But some locations and some mounts are bugged and Blizzard don't want to fix this problems. Other players may want to use some ground mounts as flying ones - it's their desire. But I don't. So may be it's time to let players decide it by themselves?
Deathwing mount is cool, but it has had bugged "ground mount" flag since it was added to game, so I had to exclude it from favorites, because it's summoned in no flying locations. Some zones seem to be flying zones, with flying artificially disabled. I.e. some no flying scenario phases in flying zones. Flying mounts are summoned there, while flying is disabled. May be it's time to fix this problems? May be each mount should have explicit "flying" and "no flying" flags, player can change as he desire?
