The new Battleground coming with Patch 3.2, the Isle of Conquest, is live on the 3.2 PTR as we speak, and we've been running some games on said Isle to see how it measures up to the current BGs. We're pretty happy with it so far -- it certainly looks great, as you'll be able to tell by checking out the screenshot gallery we've compiled for you. It shows the BG and all its sundry parts in action.
We'll keep you up to date with new Isle info as we get it. If you're on the PTR too, then be sure to queue up -- who knows, it might just be one of us you're ganking!
