I really like the idea of more places to go, to, and I think that more portals on bonfire island might also be a good idea. Why? I know I personally wantered around for like 10 minutes, wondering if that was the only place to be. I didn't know that the big black circle texture was actually a portal. Plus It miiiiight help disband the clusterf*ck of people ther. Or just make bonfire island larger...but still more portals there.
(Oh, and I haven't been on FH for a while, so I'm not sure where the portal to Sky Rim is placed. If it is on Bonfire Island...I do apologize)
