With BoBp coming and expected move to PTO as next dlc, it would be nice to give some more Soviet fighter as option for players that dont have to big interest in west front or pto. Yak-9U would be my favorit, but no maps in game where it can operate so probably only MP players would buy it, and just early Yak-9 would be almsot same as Yak-1B already available as collectable . I think Yak-9T gives posibility to be included in existing DLC in game and someething interesting compared to Ya
