I think roofed forest would quickly be burnt down to crisp, I think it only helps the attackers sneaking up, leaving the defenders no interest in preserving it, if we still had flags at least.
As for battle planning and anarchy, I think that's going to be harder, because we aren't that many on the server, so usually there'd just be one person on who could run around taking over whatever the others might've made.
But in the end it's up to the rest of you to decide how a second battleground should be, so those are just my ideas.
