The good news are that there isn't much left to destroy

The old T11 destroyed by T11 2016-17, with unity instead of flash, so we can watch repeated preset "live" animations.
The old auction system where you could build a simple 5* new 11th squad with 20 tokens or using tactics to buy or sell your players also gone.
Scouts are more expensive, recommended most of the times useless, the same with negotiations which doesn't work good.

The old training system was replaced by a more complicate but not better system where there are not ballanced skills with no effect in game play (unless the mutation effect ).

Club history was destroyed by removing the history and the take over option . At least they brought back "half" of the history.

Only associations it's an improvement and that not for high level , platinum division or top100.
