My only problem with the /ritualprayer emote is that I wish the flames would dissipate after a while (like the notes in /songbird), or there would at least be an option to toggle them off. If they add animations to the older emotes, I would like it if they weren't persistent.
But I agree, the mounts should get their quest actions.
(They should also add Orchestrion scrolls for tribe themes that don't have them yet - *coughcoughSahagincough*. It'd be nice to get scrolls for the unfriendly tribe themes too.)
