Season Two Players

If you use a Season two Player in any Ultimate Team Game, it will become non-actionable, non-tradeable and unavailable to sets. Why? They didn't do this with Season One players that I remember. I mean if I have a player that's better, I'm going to play them. Plus, not being able to sell said cards or use in sets is going to have a bunch of cards unused if you get better players. I dislike this very much. Another thing about Season Two players when I try to do the best team overall option and agreeing to use them in the lineup and played with them it takes those players out of the lineup and have to manually add them over and over again.
