Supposedly based around the Battlefield phase, contrasting the development then questing themes from the previous cycles. They mention two new keywords for the set: Ambush and Raider, however if you look at the Empire card in the preview it mentions experience…. haven't heard of this before in WHI…
Can't wait for previews… personally I hope there are some decent early defensive cards like walls or fortifications to prevent more rushed game play and allow developing strategies.
