The reason I would love to see character skins/models separated from cards is so we can buy new character skins and models directly from the Store.
I don’t mind keeping rare and random mixes on the Silver and up cards but it would be nice to have the option to buy specific looks.
This would make the players happy and give this game a very good source of revenue ( LoL and TF2 ) without upsetting the balance of the game.
