I don't find the argument that the strength stat will prove too impactful to be a convincing argument, assuming the implimentation of various proposed uses. This is because accuracy, and speed are still, in my humble opinion, just as, if not more important, speed dictating the efficiency of a soldier per turn, and its ability to engage in reaction fire, and accuracy dictating, well, the chance to hit with the myriad of weapons availible to PHALANX. Perhaps the range of things these stats influence isn't as extensive, but they are certainly no less important than what strength would impact. Personally, I'd rather have a weak trooper with essential gear, light/medium armour, reasonable speed, high accuracy and a laser rifle, than an ox with high strength, heavy armour, a bunch of additional utility equipment, a minigun, and either low speed or low accuracy (though I certainly like the latter better conceptually, lol). In short, interesting choices are good, while being able to heft just about everything your soldier's carrying space will permit without penalty is bad.
