So if they're going to make mounts useable in dungeons:

[Khalithar]

They are adding a new mode of play called “explore” mode, kind of like certain in game quests (nier storyline) where you revisit a dungeon without mobs/obstacles etc. in these cases mounts will be allowed for..well..exploring and looking around. Most likely for screenshots/posing/rp.

The mount-in-dungeon thing appears to be a separate instanced thing, not actually running around in your Expert Roulette dungeon with a mount. It seems to be under an "Explorer" mode version of that dungeon, which lets you use limit breaks and mounts freely. At least that's what I understood from the translations.

I only emphasized it in combat but I should have added it to my OP.

I'm asking for a toggle for an instant dismount to skip the little animation when we hop off. I know it's a brief animation, but it's something I've been wanting for a while. It would be nice to just hit the dismount button and the mount instantly disappears so I'm not locked in place anymore.
