I shouldn't have to dismiss my companion from battle to mount. It should just mount instead. I'm fine with using the gysahl green. Though I'd like it even better if I could just fight on the mount.

Mounted combat would be great. Also I should be able to talk to NPCs at the very least while on the mount.

Before I forget...summoning the chocobo as a battle companion should not interfere with duty finders. I can't believe they couldn't implement them in such a way as to not do that.
