An alternative could be cheap Mut 20 coins

 Auction Block adding more options and using a max bid input could be really fine, not capping auctions at Madden nfl 20 coins are great too. Really I can list many modifications on the UI side but that could take forever it's time for a change here.

Give more packs in every mode among the biggest joys in MUT is opening a bunch and getting blessed give us more opportunities for this or have like a pick one strategy" Random -- OVR Elite or Game Changer Bundle" only 1 example I thought of.This is a controversial one but eliminate them entirely and replace with two team masters (64 complete Madden NFL players) who've team boosts to particular stats for Madden NFL players of the same group (no bodily boosts though) I am attempting to escape from similar appearing squads and everybody having the exact same Tillman and Tory Holt.

In its current state it's a severely flawed system that encourages lengthy solo challenge grinding and it's only a race to maximum level. One adjustment you could make to the present system is rewarding Madden NFL players with bigger XP profits from wins in head to head, weekly battles and unique solo challenges that can only be earned once per conclusion. 

An alternative could be cheap Mut 20 coins removing it all together and move the rewards you receive from it over to a completely new achievement established system that has its pros and cons as well, I will be honest this is a demanding one.
