Select Champions
Saving shards and opening crystals and not getting the champion you want is soul crushing. Allow players to select the champions they want by saving shards. Even if the amount is 10x the amount for a random champ.
20,000 3* shards for a 3* Select Champion
20,000 4* shards for a 4* Select Champion
100,000 5* shards for a 5* Select Champion
If you get two of the same champion - it is only a 1x dupe.
You still would have the option to spin for Basic or Featured champs but you also would now have a choice of a Select champ.
I believe this type of offering would greatly increase morale and make us feel like we have a real chance at the champions we really want if we work hard for them. The harder you grind and the more you participate - the faster you get the champions you want. Hard work and dedication should be rewarded.
