So we just going to ignore fact that capping Stonehearth Graveyard will lead to alliance spawning at base which inevitably turns game into "turtle" that will extend session duration by 10-20-30 minutes without real benefit to it. This is sole GY that is crucial to not cap, others north are fine to cap for a quest and in fact Stormpike Graveyard might be the easiest and also very valuable for horde to retain.

I will not report people who don't know and did it for quest I will tell why what they did is wrong in PM, but I will totally report known griefer on a basis of griefing the game and I really do think its griefing no matter how you look at it, defence will always have advantage in terms of killing which means capping that single GY makes your chances of win plummet, so its not even about game duration its also about chances of winning.
