Thank you for your thoughtful and considered response.

I think the parent post about legendary cards (and the need to quickly release 2 new legendary reward cards when new ones were already recently released) illustrates why they needed to stop allowing potions to be used on reward cards. It was just accelerating the speed of legendary cards too much.

I am looking at your account and it is mainly Level 1 cards. You have a Level 3 Delwyn and a handful of gold foil cards. The current inflationary rating system is distorting people's perceptions of what the leagues should be like. Instead of comparing it to what the leagues are like now, I think it is better to compare it to competing against accounts with appropriate leveled decks. Although Silver 1 might be "too easy and dull" to you right now, can your Level 1 deck consistently beat accounts with Silver level cards? I think the lower leagues will definitely be a lot more lively and competitive after this Power update.
