I hope so too. Changes presented like not revealing the name before the matches will certainly help against win trading. Investigating suspicious behaviors like multiple surrenders and accounts fielding 1 monster instead of a full team should certainly be done in an official capacity.
Now, preventing people who makes the effort to learn the necessarily skill to win from earning rewards just because they can't shell out tons of money is elitist and tyrannical.
The assets that these people win are also sold back to the market, which means they aren't lost and are still revolving around the economy.
Grinders make the effort to gain assets by investing their time so they can earn food money while whales buy it from them so they get to stack up on assets without needing to do manual labor is fair and square in my book.
You might as well remove the rental system if you don't want people to rent cards to compete.
