About regular and alternative upgrades.

1. Hunters with poison and invisibility are good for final battles against archers. 2. Megeras are better than Furies in stats, except for initiative. 3. Minotaurs - Guardians: two attacks are better than one. 4. Tier 3: you can run around enemies and hit them with a stick. 5. Hydras with poisonous blood: the blood attack sometimes reaches even archers standing 3-5 tiles behind. 6. Which hero for the Sorceress? If it's the Witch Queen (I don't remember her name), then archers. If it's another hero, then Tier 3 - they can take out archers. 7. Red dragons: they have a cool ability.
