and the first record of my store is not the youngest one. Also, if there is more than 25 records in my table, I will be able to locally filtering/sorting only the first 25 records ... and I don't want to retrieve all records of my database (i.e. pageSize: 9999999?).
Another major issue is that association doesn't work because of the lack of remote filtering implementation (the game.actions() store will contains the 25 first records even records with 'game_id' != game.get('id')).
