Non Dupe Shard Packs

Hi all,

It would be a good idea to have a non dupe cromium pack, like 1pack a day with 20 shrads of heroes you dont have 7* or 330 shards or more, that way its just some shards a day and it wont be possible to complete all heroes in one day, and it doesnt takes money away from normal cromium, it is just an idea.
