Theoretically.
White fucking armor which looks like made of plastic is not cool. Most propably economically collapsed and ruined by uprisings empire (I'm basing only on movies) is not cool. And why would you kill someone with suffocation or some lasers when you can just tell him 'ur a fukken looser and a fagget, go kill urself' and he'll do it. Light side rules
obviously this guy doesn't know the power of the dark side (Ds can do that mind thing too btw). Also even in the movies the Storm troopers >rebels. Only when the hero showed up on screen did they do any real damage.
back on topic.. here's my answer to all these percentage threads.
People play what they want to play. Axis is more popular, for various reasons. For me being a military person and a history buff I like the axis war machine. There stuff is cooler. I palyed them in coh 1 and in COH 2 when they were UP, OP, and balanced. I even stuck to axis during the kangaroo days..which I hope never visit coh 2.
