Tactics for playing against a Necromancer.

Dude, you're hilarious!

That's a smart idea! But what's the point? The person wants to win against Kaspar playing as Knights. Does it really matter to them if they know that it's easier for Kaspar to play? They already know that. "Don't tell me how to live, just help me financially." Reasoning about the hero's skills won't help the person, but at least something might come of it, and in any case, it will be easier to play as these heroes when playing as Knights, which is already good.
