Retain new players increasing chaos legion packs price? Not allowing them to buy lands? They say everything in this game is to be scarce, so the players will follow these words; The justify to increase the cards packs is to make new cards expensive at the beginning of their life. A Kron that used to cost 4 bucks and now is 400 USD is not enough to see the prices going up? The question is that buy a spellbook is easy. But many people here leaving the game because they are paying to play at the bronze league. And those who invested in SPS lost a lot of money already. A couple of reward cards gained in one chest per daily quest will not change anything.
A game of cards where those who have more cards gain more cards. And the novice players can now buy cards for an expensive price. The diamond-champions will get 90% of the cards. If you don't help new players to buy cards to play a game of cards, the will be scarce quickly.
I get your perspective however you have to balance things in the game. We can’t cater to new players constantly in the form of lots of things up front. That would incentivize people to just create lots of accounts to take advantage of the better rewards for lower leagues.
As with anything, scarcity will drive up the cost. I could have sold my gold foil Kron for 250$ back when I got it but I kept it knowing that it would go up in value. If you see short term gains over long term gains you will most often lose out.
The other aspect of this is that you can’t give too many things out for free. It is a pay to play and play to earn game. That is not at all hidden. You can join and enjoy it, knowing that up front or you can stop. There are a lot of people who joined at a time of very significant change and if they stick around, it will get better. The changes to reward card drops will improve that.
