Mod requests (orders).

Okay, I'll check it out. I remember seeing a mod that integrates knights into the upgrade roster and moves dragons to the neutral units. How good is it?

This is probably about the Dark Champions of Necropolis. The mod is good, but the unupgraded knight starts flying on a horse.

There was also a mod that moves undead to Tier 7. I played with it for a very long time; it's a bit buggy (the red griffin instantly exits its dive attack), but it's good.

Both mods are in the "Heroes of Might and Magic 5 - Modding" thread.
