i'm embarrased to say this, but i miss 90% of the alliance tunnel jumps on my female gnome :$... works fine on my worgen druid, and even my worg. warr.. :S
The only Horde jump I can't get on a Blood Elf female is the right side of Horde tun, I can jump to the rock but then getting up onto the big tusk thing never works, I could be just messing up though.
