Blizz did not do a great job in explaining why they lowered WSG gy. First they meant to say they wanted to stop the flag carrier from sitting in their own gy so when people rezzed they were right there to protect the fc. The reason they did this was because of rated battlegrounds in my opinion. Lets face it in pugs it really doesnt matter that much when the fc sits in their own gy. I have been in a few RBG"s where that was the opposition or our strategy to sit gy so when someon did rez again they were there to help the zerg or heal fc if needed.
For RBG's it makes sense. For pugs it can be a farming disaster.
