I think people are remembering the Chocobo animation in FFXI with rose tinted classes. Don't you remember the black screen and then popping up onto Choco back after using whistle?

SE are capable of making a 'running towards you animation' plus a cool 'mounting animation' even while running, but it looks like Yoshi-P made the decision to have insta-pop-mount-to-please-the-silver-spoon-fed-care-bare-hand-holding-WoW-spoiled-"takes too long to mount"-cry-babies. Yea, that's right, you know who you are!

We have also yet to see the dismount animation.
