They should have made WG an AV type area or added another 40v40 or even a 80v80 BG that was an instance - NOT a world area.

When they make Wintergrasp marks so valuable, and none of the other marks worth anything, then EVERYONE plays WG - not sure what they expected.

100+ v 100+ battles never worked in wow, and I doubt it's going to be an easy fix to make it work now.
