I've literally never seen you spout any original idea. I've also never seen you say anything other than your idea was the best idea. I personally think most of your ideas are just re-vomited jargon from the internet for the most part. Yes, the war machines can become magical. Guess what that means. You now have to waste your war machines on ethereal units. Ya, a GW lord is great. He has 4 strength 6 attacks. Guess what else has 4 strength 6 attacks. 2 Hammerers.
My problem with you Hero, is not that you may be right. It's that there is no right, it's all opinion and conjecture. That and every time you type you come across as a real prick.
