I spoke with one of EA game reps (from my dot.bomb haydays as editor of Combatsim.com) The way the game works is that as you gain experience, your shooting ability and accuracy will increase. You'll be able to add more individual tweaks and mods in the 40 locks to improve your soldier.
How that could translate into FS? Good question - maybe similiar mods but renamed. The PERSISTANCE idea is great - and could be easily translated into our mod.
Yeah, BF2142 ROCKS. I haven't had that much fun since BETA 1 of Galactic Conquest.
