After watching the videos on siege battles, which are just copy pasted designs that involve bum rushing walls without really having any ability to strategically plan, makes me worried. It is a huge change from previous games that seems like a really bad decision, and while I've never played Attila I think it was, city razing seems like an odd concept. The one screen shot that was released that showed half of the empire had been razed by various NPC factions seems like a really powerful and likely problem. Why would anyone attack a faction they cannot occupy except to clear their borders by razing everything?
Furthermore, the lack of ability for the great modders in the community to have any creative impact on the game is also a little sad. A lot of people really enjoy large, large scale battles. I hope that the ability to increase unit sizes/stacks will remain in the game. Because of these reasons I've really thought about just getting a refund on my perchance and just sticking to Call of warhammer.
Other thoughts?
