Turkeycat, what I don’t understand is that you think the time to create new rewards is the issue, If we check most recent mount achievements are just recolors of another mount, maybe creating new unique rewards could be a time constraint issue but as I mentioned in my old post, Devs can use old recolors that are in their database but unused at this time.
For example, new mount achievements for X amount of mounts or some new achievement like Awake the drakes could use those recolors. I don’t know for other cosmetics but at least that’s my feedback regarding mounts. I don’t think that time is the issue regarding the rewards but their conflict of philosophy between Items that were removed and the actual amount of items in game.
PS: I wish time was the issue and everytime a new mount achivement was introduced, it was an unique mount that the model only exist for that achievement. That’s such a cool idea.
