Reshcke,
I agree that it would be nice to have a new map to go with it, but like you said that is not likely to happen in just a matter of a few days.
The map to me isn't quite a concern as the planeset involved. If there is a better suited, existing map, even if it may be of a different region, I wouldn't be opposed to subbing it in.
But it was Warloc's setup and Guadalcanal was the map he picked.
