Umm, two pieces of non-constructive criticism you can't build forges on your lands until you've unlocked 9 (I think) lands. The highland price numbers go 1, 2, 3, 3, 4 xP other than that it's an awesome guide will point newbs in the direction of this thread
Ooh, also, the epic battling will encourage a hybrid build so there should be info soon (if not already) on that topic.
I've found that a good build ( for the war banners ) is 1 defensive tower 1 spy tower 1 balanced build and the rest attacks
