CA seems to have taken a step backward with the multi hit point approach to units like elephants. It makes them LESS vulnerable to sharp pointy projectiles. You end up having to wipe out almost the whole unit's hit points before you start getting kills. It collapses rapidly once it starts taking casualties.

Some of the same applies to chariots. What I think we should see is the mount breaking down (elephant/chariot)...even if the men aboard don't.
