Why not a Nats mark or a firelizards? I would go with the 2x Choas's for level 2 ww and more chance to cast frozen orb. Bramble is a good idea, but thorns is soo cheap. Enigma would be the best cuz you could tele and then ww, sort of like a barb with enigma.
I've seen it done like that, but there's no real point in telie when you can use DF/WW. Using 2 Chaos is a total waste. Personally I don't like Fury claws, but eth tucs are really good. NAts totally sucks ass.
