Chariots are pretty much a disaster on all fronts, whether fielded by oneself or the enemy. When playing as Egypt or Britannia I lose more generals due to the fact that they are charioteers. I also lose more of my generals when facing Egypt or Brittania due to them coming into contact with enemy heavy chariots. Chariots also have that annoying habit of running amok every now and again as well as liquidising themselves against the odd phalanx.
