I dont usually on here but a few things that I thought may be well received:
Make TOTW actually the team of the week meaning mid week league games count so run TOTW from Monday to Sunday prior to that TOTW.
An additional option for a mixture of untradeable rewards and tradeable rewards
FUT Champs rewards
Make previous special cards available in player picks from time to time so that people that have missed them may get a chance to pack , such as FBs and Futmas cards (still untradeable)
