Now that I think about it though, while an 'animal-leadership' rating might tame elephants/mammoths/ to some extent, it doesn't necessarily solve the problem of a trampler rush.

Many nations can put together a rush based on chariots, troglodytes, or minotaurs. While you might categorize the later two as animals of a sort, where do chariots fit in? With the right scales, they can be just as nasty as elephants - they're cheaper, and often have better moral and protection to boot (I scoff at your slings and arrows!).

Maybe units with long weapons DO need a bonus against tramplers (heck, and charge bonus units while we're at it!). It would give us a reason to actually buy those pike-men/spear-men...
