Why can't there ever be a deal for class selective 5* awakening gems 😔

I know that 5* awakening gems are rare to come by but wouldn't it make since to have such a deal in the store for people to have a chance to buy one to bennifits their important 5* champs and just looking at the daily card deal with the generic 4* gem and 2 per day generic 4* signature stones and handful of 5* signature stone crystals you could have easily raised the price of the deal and put a generic 5* gem more people would buy it 🙁
It's just a game over all I'm just idk
