So I usually put a skink chief on a stegadon, but lately when I have the big guy charge a unit he gets challenged and all my impact hits and stomps go into the challenge and not the unit. So the stegadons glorious charge is all wasted on one model. Should I be running a steg without a chief on top to avoid this and put the skink chief on a ripperdactyl? I assumed the extra leadership and maybe a magic item on the steg would be worth it but now I'm not so sure. What does every one here think?
