Tactics for playing as the Sylvan faction.

What does the number of druids have to do with it?

That's not what I meant. I just meant that your opponent, no offense, is a noob. You could have just cleared out the neutrals and then said that Chaos isn't effective against Elves. I showed how it's not effective: a ballista took out 100 higher vampires in two shots. And in general, you need to consider against whom such a tactic is effective. It's not very effective against undead due to their large armies and the ability to significantly reduce the defense of the enemy. But against humans, I would try it.
