I disagree about the arguments being said that there needs to be a combat focused edge (no pun intended) to this because it's "Star Wars" and not "Star Peace". Well yeah, that's true, but correct me if I am wrong, didn't Dungeons and Dragons not always have dungeons...or even dragons?
Point is, people look for different things and you can't always focus on the combat side of things.
However, I personally think that the argument that things are combat focussed is a little stupid. Dangerous Covenants focused on it because it is the sourcebook for the HIRED GUN.
Furthermore, more weapons, attachments and vehicles help add variety to the world and its nice that most of the weapons/vehicles introduced in each sourcebook is appropriate for the theme of that book.
