And I just found the Hero himself "Admiral Odesyus"
What are the twin peaks you ask? Let me elaborate further.
Anyways, this new battleground is going to be a capture-the-flag-style battleground (similar to Warsong Gulch). The basic concepts of Warsong will also apply here (ie. flags are located in the enemies base, they can be returned and first to 3 wins).
The terrain will be built in an asymmetrical manner so that one side doesn't have advantages over the other and from what I can tell it will look similar to this:
All in all I think that this new battleground will keep the fun 'capture the flag' concept alive while also adding a few much needed changes to keep players interested.
