I'm almost 30,000 XP past level 30. Mainly keep going on the chance that XP Carrie's over but knowing EA it probably wont despite the game telling us new level achieved multiple times after level 30.

I predict season 2 our XP will not carry over from season 1 but I predict that season 2 XP will carry over into season 3 but EA wont tell us and no one will bother doing it since it didnt carry over previously.

Would be a very EA thing to do with their outstanding communication with their community!
