read the article, and understand it. Tol Barad is a mountain of fail. Winning on D is so absurdly easy that the only time the Offense is going to win is when the Defense is so monumentally bad they cant even figure out that they only have to zerg around and keep ONE node half-capped to achieve victory. Given two equally matched groups and assuming that in all but 3-4 cases so far, stupidity has been at normal levels on both sides, its a simple game-mechanical impossibility to successfully attack the place.
Then also understand one more thing:
This dumb thing you do by leaving the raid after you get an HK? It isn't doing anything.
five times yesterday i did the following simple test - during the battle, do a /who tol Barad.
if you have one available, do a /who Tol Barad on the alliance side. Provided the number of people in the zone is below the 49 person cap on results for /who, you will notice that they are exactly the same at all times.
All but one time, the number of people in the zone never broke the 49 person cap - and all four of those times, the number was exactly even for the entire battle, regardless of this "leave the raid after an HK" myth.
So just stop.
