Commander Farsight. Incidentally, I meant him, when I mentioned Tau. I know that if I ever started Tau army, he would lead it. He is so much cooler than all the other HQs combined
Also, I have checked, and it appears literally no one can take free LoC. C:CSM doesn't have them, C:CD doesn't have GD's you can upgrade, C:DH doesn't have stats for such an upgrade. So, it's paper scare.
