I'll also note that ultra-cheap low-prot units like militia or R'lyeh's freespawn cultists can be useful as lance absorbers; the heavy cavalry's initial charge can be quite threatening to even well-protected (and generally more expensive) troops.

Other things to pay attention to --

- If you have in mind particular spells, check their ranges...
- Damaging auras. Friendly fire isn't.
- Flyers essentially teleport, unless there's a storm going on, and some can even fly during storms.
