I've been for and against the TBD over the years; we had many plane sets that require more attention then something that could be nothing more then a "Hanger queen" unless its a scenario, but honestly we need to start having these "hanger queens" because frankly it has to fill the gaps left in the plane sets.
I still honestly want to see some other plane sets added; D.520 for example, Beaufighter - planes that would serve a purpose in scenarios and in game. TBD is important yes; however other considerations like more Japanese aircraft to fill out its plane sets would be nice.
