Thanks for your feedback. In general, we look at the features we add in terms of the overall health and longevity of the game. If we feel a new feature or award provides something of value to all players, we will consider putting it into the game.
In the case of temp awards, they might be valuable depending on how they are used. They may potentially enable us to provide more desirable mods, for example. That said, we don't have plans to implement into Crime City at the moment, but there maybe a gameplay or system balance reason for us to implement it in the future.
We do value long term players like you as well as newer players, so we'll do our best to introduce features that benefit everyone.
