Late-game Town Enhancement.

I agree about Waishan; he greatly enhances the Rangers, and the Sharpshooters develop excellently, making him one of my favorite heroes. Regarding the Furies, it's not entirely clear-cut. If you have artifacts that boost Initiative, I think the alternate upgrade is preferable; they are tougher and have higher maximum damage. Concerning skills, Luck is definitely useful (Lucky Charm), but what about Logistics? Unless you're going for "Keen Mind," the first-turn advantage is nice, but I'm not sure it's worth taking Logistics just for that. However, "Surprise Attack" is another option, and of course, sending Hydras to the enemy's rear is not only tactically advantageous but also a psychological attack. As for choosing dragons, it depends on whether the opponent has Berserk or Subjugation. If Dark Magic isn't your forte, Red Dragons are preferable; they have higher Initiative and can be used as a powerful strike force at the beginning. With high attack, they can eliminate one or even two stacks of enemies in a single blow, and their ability is excellent. Fighting against Inferno is generally difficult; they have Imps that can drain mana, and a Sorcerer without mana is useless. However, Banish is indeed very useful in this situation; you're right, dark_elf
