Absolute horrible changes. This is a huge joke. I can understand decreasing DEC rewards. However, the end of season changes is really terrible. Last season, with better odds, I already got only DEC and useless potions that I can't trade or sell. Now you're saying that instead of DEC I will get credits and the chances of getting cards is super low.

If you're gonna do this, at the very least, you need to decrease the power requirements for the leagues. I have enough rating for Silver I, but only enough collection power for Bronze II. The gap shouldn't be this big.

This is also a huge blow to anyone who bought multiple accounts expecting certain rewards and suddenly they are getting cut by like 90%.

This was already the slowest progressing game, by far, I've ever played. It doesn't need to be slower. You say it's not about "new players" but about holding assets or not. You can't really expect people to spend thousands to aquire enough assets to get out of winning fractions of cents part of the game. New players didn't have a chance to get those assets when they were cheaper.

You compared this to MTG, but it is not a fair comparison. I played the game seriously for over 10 years, so I know the game really well. Sure, you can't really compete with a $20 deck. However, some good decks cost between 100 and 200. Most decks cost 300 to 400. Sure, if you move up to more open formats with older cards, prices go much higher. However, most tournaments are done with just the most recent cards. You can't really compare that with a game that has individual cards that cost thousands, and that's just for a level 1 card. If you win on MTG with a cheap deck, no one is going to check your collection to see if you have spent enough money to be allowed to get the prizes or if they are going to be lowered.
