Of all of the interesting lands of Ulthuan, Chrace has always been rather under represented considering how it is a land of warriors. The new Lion Chariot looks interesting, though. Think Tiranoc Chariot with big lions - as in really big.
We're talking S5, WS5 and two attacks each from the things pulling the chariot, plus two elves and potentially some scythe hits! As a chariot hit, that's going to hurt, and it has extra rules (including causing FEAR) on top of that.
My first army was High Elves. If I got the time and money to go back to wargaming and Warhammer then I'm not sure if I'd update them a bit or go for some Orcs since I like my Orks so much.
