im experiancing them quite a lot, usually at least 2 units in a arverni army with bronze upgrades and 1/2 experiance as the casse.

i pin them with calawre's (i have 2/3 in a army just to deal with these gits after a horrifying bridge battle with my army being mala thingys and bolothras (sp) i got pwned by 2 units of evil naked men) and relised chariots are my friends (i disgarded them before from RTR/RTW) and give a moral bonus/scare infantry. and when the rest of my army has taken out the enemy, i gather round :)
