I think its good they are trying to address the issue. If its the best way? Time will tell.

I'm all aboard for any attempts that blocks the cheesy tactic of "lowering team power to manipulating the seedings, once the seedings are done go to your reserve team spend greens like crazy and upsell your mutants to your main team, dominate the season. rinse and repeat".

It's a start, but its still Top Exploit 2018 until they fix other fundamental issues. my 2c
