I'm not a personal fan of trait-edited rosters. I understand the concept but disagree with the execution of many (i.e. blanket-deleting traits from all players). I DO agree that some traits are overdone in EA's rosters (actually tweeted Clint about it earlier today when I found a relevant opening), but I don't like it the other way either.
Here's the thing though....if you're having fun and enjoying the game, roll with it. I'm not going to tell anyone how to enjoy the game. Just understand that I do all of my testing/playing using EA's default 75 man preseason roster and that there COULD be differences in outcomes due to that....
