Mounts were a great addition that I enjoy. Maybe add a way for us to get mount skins from areas other than the gem store?
Home instance QoL updates would be nice to have. With PoF, we have even more books/temporary books and it would be great to centralize them in our home instances.
In general, it would be great to earn more unique rewards from unique content. Say, a mount skin or mini from a series of puzzles. It just seems like too much acquirable content revolves around gather gold somehow > buy an item or series of items.
