Which is a self defeating idea, of course there will be nothing but amraam slingers if people go out of their way to make relatively obscure ARH capable variants of legacy airframes and neglect their prime timelines. The F-4E is a 60s/70s airframe and to claim it doesn't have era appropriate contemporaries in DCS is being willfully ignorant at best.
Currently in game or under development are the MiG-21, F-5E, Mirage F1 & AJS 37 (which is nigh identical to the 70s AJ 37 if you restrict its loadout). All of these are mid '70s birds, and will likely all be in the game before the F-4. Is this really not enough opponents to fight?
