those guys could be the reason the Vanu left their planet cause of these things. This would be a good thing for those gamers who dont have alot of time to play as u dont have to hack anything and all u do is fight now they would be small in variety so not many people choose them they could 'morph' instead of getting weapons they could 'morph' or 'evolve' into new creatures so instead of certs they could have umm........
