i have also been contemplating on my new exodite army for conversion ideas, basically in the fluff they are very powerful and have had great success settling on there world of *insert name*, and have even been known to travel in there own fleet ships similar to craftworlds but much smaller to wage war and claim new territories on other planets. they dont lack technology but usually their skilled warriors prefer to get upfront and personal.. while ofcourse others have emerged out of there society who prefer to fight at a distance, and do it very well. another main point is that they use kroot for the frontlines of there armies(basically a meatsheild, but still a very potent one if left ignored)
anyways i plan on having a farseer riding a terradon as a jetbike, and hes got a dragon head as a helm righ tnow that looks great
i too was thinking of using cold ones for shining spears,
ive thoght about using a dragon for a wraithlord or something too, as a wraithlord i could have like a rope tied from him to the farseer so he would be like leading him (wraithsight) ive got plenty of other ideas but i really gotta go to sleep...
