GSF seems to have a bad case of WoW syndrome. That being Horde always winning, and Alliance always losing (unless they've got a great premade). Horde being, in this case, the Pubs.
What can we do to combat this? The only thing I can suggest is roll with some friends, converge on one target, and have great communication. One thing I've noticed playing both of these games is that the pubs are more vocal during PvP matches. Imps are quiet, but usually know what's going on. This needs to change, start communicating little sith!
