Interacting with NPC's while mounted

[Bluevann]

I'm just curious as to why they don't allow us to turn in or accept quests while mounted.

They made it like this because some times talking to an NPC will prompt a cutscene. And in said cutscene, you will be shown on your feet, not mounted. I don't really know how the mechanics work, but since the CS uses your current character model, I could see a mount possibly affecting the way certain parts of your model will be displayed, aside from the much more obvious "wouldn't make sense for your mount to suddenly vanish".
