At this point we now have a plethora of upgrades (mainly officers) that can modify your command dial stack. All have they're advantages, and disadvantages (mainly cost and opportunity cost).
But I noticed that if you run a Skilled First Officer at 1 measly point, if you run ship based around two primary commands, you can always have the desired command available. Example being Nav, Eng, Nav... Need the Engineeing command, toss the top dial, and set the 2 dials to Eng and Nav. Next turn your again Nav, Eng, Nav. I find this highly attractive for gunship ISD or VSD (all navigates & engineering).
This also turns two command ships into single command ships.
I think this is a rather spectacular upgrade for its cost.
Edit: The attractiveness is the thought process the creator of the gencon special had for commands, simplify your decision making.
Edit 2: And it's a discard effect which makes my initial thought a useful one time effect, vs an almost broken repeat effect. (Reading comprehension -1)
