It's not entirely about better definition (of current dev-given traits). If they want to add variety (ie: more cohesion and fun) but keep the current "balance", they should move away from strict faction-specific traits and go more towards lore or theme. TR would be much more interesting if they went more towards rockets, gatling guns/miniguns, missiles etc.—generally a saturation of bullets, missiles, and explosions. They are supposed to be a professional military after all. (I would be especially love to see some MIRV-type weapon for the TR). NC should stick with hard-hitting/tough defense, and stick towards the railgun/gauss route. I can't really figure out their theme besides that, but they seem to be a midway between TR and VS in terms of technology, although they strictly stay away from anything alienish. VS probably have the most potential for variety, since they are future themed. Where are the fusion rifles (devs shouldn't just slap on a different color and sound for the bullets and call it plasma/lasers, although the lasher/PPA is probably closest to the theme)? Limitless energy (the ESSR finally touched a bit on this)? Hovering buggies (if there are magriders, there should be at least mini versions)? There is so much inspiration they can draw from other games that it disappointed me the first time I tried the VS (and NC/TR). The devs could be much more creative with the designs but just won't go that extra step.
