Discussion about Heroes 4.

Guys, the AI's behavior in the game is annoying. Are there any patches or mods that improve it?
Examples:
1) The AI doesn't buy creatures in the portal.
2) The AI often doesn't claim mines, doesn't collect resources, or artifacts.
3) Strange AI behavior in auto-battles, especially in the selection of spells, ranged/melee attacks, and when defending a castle, the opponent often just stands there.
4) In quick battles, the AI manages to lose against an overpowered hero who is difficult to even scratch.

I also don't like that you can't stop necromancy and summoning; sometimes you really want to disable it... If a hero is traveling alone, it makes you not want to take Nature or Death magic, because sooner or later you can acquire those skills.
