Maps, weapons, special events to earn them if you don't buy season pass.
What I would hate is that season pass only gives you the opportunity to grind for the content before everyone else.
I can see each season being a real grind to help keep numbers up playing.
If EA had any respect for it's customers it would make it quite easy to finish but EA does not respect players as we have seen.
Also each season pass should not have a time limit.
So players like me who cannot play every day and dont want to should be able to finish it whenever we like.
