My recent research indicates that promotions are based on a formula that is not just based on "performance" but is heavily weighted by stats. Once promoted to squaddie, even if he's not doing anything, the fact that a trooper just has better stats is what gets guys promoted. # of missions and # of kills is a factor but promotions gets wierd because those seem to be heavily outwieghed by basic stats. I'm sure it'd feel more sensible to me if the first promotions were over-weighted to number of missions and kills rather than high stats. Better stats should be downgraded in importance to being closer to a tiebreaker between promotion candidates and a captain who sits in a base accumulating no mission credits and no kills should NEVER be promoted over someone with more missions and more kills. Continued performance should be necessary for continued promotion. if that formula can be changed that way then I will no longer feel that all promotion authority should be taken away from the game engine.
