Exactly as i said...GLA may be slightly underpowered but in general, it may just be that one might like

or dislike

a certain army.
Such as: If you are american, then your first choice would probably be america.

If you are asian, than you would probably prefer china.

But if your from the middle east, (which i dont think anyone who has this game is) would pick GLA.

MOST OF THE TIME!
Sometimes, if you play as one army and win once or twice, then you stay with that specific army all the time, and hardly consider other options, unless you get bored.
But, in truth, there really is no
huge difference between them :| , which is why when I go online, i choose random and then stick with that army, until i feel i should create a new account because of boredem or unsuccesfulness with them.
And a brief summary of that is...IT"S BASED ON YOUR OPINION AND YOU!!! NOT THE ARMIES OR THE FEATURES THEY HAVE!
PS. sometimes it is also based on the missions, or skirmish's.
Oh an toyLus, not to offend you but the word "races" is kind of being a racist. :dead:
