So the reason we're adding Forbidden, Calamity and Raider into the story this early is so that ZAFT actually has more Suits to steal and ORB/the Earth Alliance doesn't keep all their toys? Just wanted to clear that up after going back through the OP.
I guess they'd have to be toned down to similar levels as the original G-Weapons, since that'd make sense given the timeline and the tech available at the moment. I wasn't sure if we were starting way back from the beginning of SEED.
