My lowbie shamans finally caught up to my other team and I wanted to run AV for a bit. The other day I queued up and both teams got in. When the gate raised I went out and hit my mount macro and only one team would mount. I even manually clicked on the other team's macro and they refused to mount. I also tried via the command line and it wouldn't work.

Ghost wolf worked but that is not adequate to get across the BG fast enough. Has anyone else had this problem?

Here is my macro
Code:
/cast [nomounted, swimming, nocombat] Abyssal Seahorse; [nomounted, noswimming, flyable] Celestial Steed
