Ah come on, those Spiders are a huge investment. Of course they are going to do a bit of damage, but they cost a small mountain of gold.
Besides, you haven’t brought out your big guns at all. You have a huge communion force just hanging out, not engaging. When you come in, you’ll probably drop mistform on everything, not to mention making everything etherael and lucky.
I will lucky to hit anything, while you wipe me clean with Thunder and Frost.
So far though, I have avoided most of your major forces, which is why you have an army of decent size grabbing up all the territory around my castle. I don’t have anything that can engage without being pulled apart by your Harbingers.
My only chance to to weather the upcoming siege that I believe is coming.
