They should concentrate on Madden 21 coins one game every five years or so, then update the rosters perhaps via DLC. That way they can have more time to implement new capabilities.
Also, I truly miss NCAA soccer games... There would be fresh rosters every year, but the game would feel different every year. I just believe the old xbox times of pumping out games annually is getting old for people now.
One game every five years also would mean people wouldn't have to restart their MUT teams every year. You're right, of course, that a new release schedule could be a huge advancement --If EA managed it professionally.
However, what they'd inevitably do is charge $20 for new rosters, find a new way to milk MUT, and make few to no modifications differently. It wouldn't result in a better match. It would just change the way players get screwed.
Personally do not think the game is buy Madden nfl 21 coins that bad, but maybe past encounter with more glitchy game series is clouding my judgment.
Until it will become second nature for you and you have to consciously prevent yourself from creating puns so the people today dont stop talking to you. I am speaking from experience btw. Puns, such as anything, are good in moderation.
