Jimmy please remember how long it took for the XBOT DEV to join the team and actually get to work catching cheaters in ranked.
TOS doesn't mean anything unless it can be enforced. They will just make more accounts and try again to beat the profiling that was developed to catch them.
Bringing back league level card caps will reduce the complexity for each league and make it easy for battle helpers to always win as they operate on brute force simulations of the number of possible winning combinations.
Before the XBOT DEV got to work I could tell there were people cheating in ranked. They were not accounts engaged in proposal conversations or discussing things on youtube videos from content creators they were just accounts constantly winning.
Before league caps were removed I was pushed all the way to bronze even though I had a diamond deck. That was botters.
Saying you can "pick your own league" doesn't mean anything. Does the rating system get removed? No. Can I pick Champion with level 1 cards? No.
I didn't sign up to play cheaters using battle helpers. Bringing league level caps back will waste a lot of developer time on a cat and mouse game of them trying to catch the battle helpers in modern ranked. Especially if survival mode gets removed.
