Declining functions

Edit: constant shutdown of app when trading certain channels or sets, certain channels/sets are steadily rising in cost & "exclusivity" so only coin buyers can complete sets. Stop slanting the app to purchase or dont play.
Ive stopped collecting any channels that begin that bias.
Love the app, just with we could have the option to sell duplicate cards for coins or a way other than offers to get more. Specialty packs go in less than 3 minutes sometimes and then theyre sold out. Or flash sales in the middle of the day while ppl are at work.
I would really love new channels.
Supernatural would have quite a rabid fan base, as well as The Walking Dead. Dexter would be another great choice.
