What kind of magic do you like?

a) Wouldn't it be easier, for example, to take down your druid with an Ice Bolt, at least injure him, or use spells to move your creatures around, clearing the way to your druid, and then finish him off with your own protectors, like Elven Archers? You wouldn't put them in the front line, and they can shoot at you with a double shot. Without the druid, your army becomes weaker.
Regarding the Chaos Druid, what will you do against a player who is clearly smarter than the AI?

Let's say the druid is alive and even has Immortality :) Besides, I rarely summon Elves. I'll summon Satyrs on my first turn – if I'm lucky, they'll lower the morale, then I'll summon a few not-so-strong infantry stacks (Hypnosis only lasts for 3 turns, I think), the mage deals with them, and don't worry about the druid – he has Immortality. The mage won't be able to cast spells on anyone important because half of his creatures will be stunned. Then, I'll try to have at least two units with high movement speed harass the mage :smile34:. I don't think he'll be able to take them all out :p
And there's nothing you can do against the Chaos Druid :p You position yourself further away, summon Manticores, and that's it. The Chaos Druids won't fly far, and the druid won't be in danger, unlike the poor little dragons :smile34:.
And don't tell me that Order is better :p I'm just inexperienced; a more experienced player would crush Nature with Order :p It's about balance, you see
