Fully agree on the 2-seater. In fact this is part of a wider issue mentioned in the "second look" article: the focus of the planeset. Since the primary focus of ROF is the final year of the war (judging from the game map), adding a Nieuport 11 or Fokker EIII seems a bit pointless. I'd much prefer more late-war additions (even if only as AI) before they start focusing on other periods.
That's the main reason why I stick to OFF for now.
But that new career mode looks too good to pass on, and with its squadron management and waypoint options it's a step ahead of OFF.
