Unique Fed Missions worth playing: 1-2. Project Nightingale gives decent cannons, that Phased Tetryon Mission might be useful.
Since you don't get access to set gear until Rear Admiral, the Efficient Engines reward is still pretty valuable. (Well unless you're running and re-running the Breen or Jem'Hadar FEs at ever rank level, but that's got to be boring).
Also, these ideas aren't really constructed for you and your desire to burn through yet another ALT on your way to assembling two dozen different Dilithium Farmers.
The idea here is to complete a faction to make it playable from level 1, for new players. To expand the ranks of the KDF with people who are new to the game (as an F2P game it will gradually but consistently attract new players), so they don't have to run through all that fed content first just to even sniff the inside of a Bird of Prey.
I'm sure a tutorial would be worthless as a tutorial is there to educate you in gameplay. Not really needed for all those at level 50!
Have you actually thought this through?
One of the things that very possibly prevents and kind of serious influx of new players is that it's IMPOSSIBLE to make a new KDF char from the start.
To have an equal chance to start from 0 with a KDF char.
For THAT people need a tutorial for the KDF.
So how about you stop thinking about your own immediate concerns and think what this entire FACTION needs.
