Forgive me for trying to be helpful. Since you are a new member of the forum and did not specify what your previous level of experience playing with Empire is, I figured that some general tips might be helpful. Obviously my bad. As a general piece of advice though, if you are looking for help and advice from people on the forum, being churlish when people offer it is a good way not to get any advice in the future. If the topic isn't getting you the help you need, politely trying to refocus it is usually a btter way to win friends and influence people, rather than telling them you are completely uninterested in what they have to say.
As to your specific point, I'm not sure why you have bothered posting it when you clearly have very definite ideas about what you want to do. Of course blocks of greatswords are a viable alternative. Yes you get less attacks and hit last, but you get better armour save and do more damage. They are particularly useful against monstrous inf/cav. It is a pretty straight forward trade-off and since neither is game winning or breaking, you can crunch the mathammer, or go for which ever suits your tactics/playstyle/army fluff. If you want to play greatswords rather than state troops, do it, they aren't going cost you the game by any means.
