Once people accepted the -that horse- in Wrath of the Lich king this has been a long time coming, more mounts and pets were added and now transmogs are added more frequently.
Expect more to be added in there, they have to compensate somehow by the loss of active players.
The removal of a the spit emote was done to protect players that spend a more premium amount on the game, this is indicative of them starting to pander more to whales or just people who want to spend more. Any expansion now you will see a a multi tier expansion release with gameplay benefits followed by gameplay benefits in game, not that it really matters ever since the wow token the door has been wide open for P2W practices that devalue the accomplishments of others in game, something they will never return from.
