A little suggestion about the cards from the arcade version

So, first of all I have been seeing posts about scanning the cards that you got from the arcade game in Dave and Buster's and I think it would actually be better if you could use the cards from the arcade game or like that you have to scan the cards every time you want to play with the cards. If this feature is added to the game, it will be so much better. I don't care how long it takes, but please add this feature. Again, PLEASE

If I’m correct the best you can get from the arcade game is a 3* and 3* champs are very difficult to use in End game content, unless you use specific champs. Yes it would be helpful for mid-early game but if you are struggling stronger champs aren’t going to help as much as getting more skilled would
