Interesting, I think the Dragon center board is a bit boring for this kind of thing, I think an extra Highlands works awesome. But for someone who doesn't wanna spend the extra money it would work. Still debating about creating a new board, or using someone else's Dragon board that is already made...that fan created board would also be better than using the center board, in my opinion. However I don't like the 2 endings and would replace them with 2 random Dragon Lords.
It is nice to see someone else using a 2nd edition board to play 4th edition! I recently stopped doing this cause I bought 2 new tables.
