When the casting time change to ground mounts in Patch 3.2 was announced, Eliah Hecht, Michael Gray and I had a long debate about why they wouldn't have applied the change to flying mounts as well. We ended up coming to the conclusion that they were avoiding it for PvP reasons; only needing to be out of combat for a second and a half to mount up and zoom off to escape a fight that's not going your way would be a little... cheap. The outlier here was the Druid Flight Form, which is an instant cast spell. Everyone but Druids hate that though, right? It's pretty freaking annoying when you get into a scuffle, you gain the upper hand, and then the Druid just runs in circles like a headless boomkin spamming their flight button and hoping it eventually takes. So we figured that didn't count. It was a perfect example of why being able to fly away quickly was a bad thing.
Boy, are our faces red. Flying mounts get the 1.5s cast time now as well. Sometimes trying to figure out Blizzard's reasoning doesn't really pay off. I'm not going to complain that much, though. I certainly appreciate being able to get into the air faster!
