Those light chariots are absolute gems. Especially in the early fighting, when there are often no opposing archers.

My starting chariots are at 1 and 2 silver chevrons atm, and great for catching routers and pulling opposing (mostly gaul) armies out of position.

Woad warriors seem like a waste of space once you can get swordsmen, and I refuse to use those silly head-hurlers. I heard of someone who modded them to work like a legion - tossing heads for a morale loss and then charging - and that seems so much better.
