I think most of them have been discussed in the suggestion forum for some time.1. People was complaining about tanking teams so they had the salary roof.2. People was asking for better ways to train so they came up with cross training.3. People was complaining about better protection of NT players so they made so all fired players end up on the TL.4. People was complaining over that the best players(highest salary) was not used as the best players in BB. So they cut their salary a bit more then other players.5. People was complaining about long time injury's so they made them go away under the off season.6. People have been asking for more stats/ranking forever so they implemented some more.
