Far Seer sometimes for me 'cos it seems to be the best at hitting flying with Orcs (besides Raiders and Wyverns), but the rest of his stats suck. He can't attack like the TC and the BM can, his Defense sucks, and he's too fast for his own good. On the other hand, Chain Lightning is great, and Feral Spirit is great to distract. I prefer BM 'cos I love Mirror Image with a Level 10 BM at Level 3 Mirror Image, Bladestorm devastates bases like hell, and Critical Strike roolz. Besides, most good Orc units are Melee, so it doesn't hurt to send a BM or TC with them. And 90% of the time Melee with kill Ranged. Just remember.
