You must be new to the game.
I’ve played since the BGs were first patched in. GY camping goes on all the time and has done over the years. Of course back in those days people didn’t cry about it. And since there are several gys throughout AV they all got camped at various times throughout the meet.
The AV gy that got camped the most was the one right before the bridge. People would stand on the hill behind it and rain down havoc.
It’s all just good clean fun. Maybe people need to grow tougher skins.
By this logic, people can also claim that being killed in BGs is “ruining their experience.”
I don’t know where you get the idea that “there’s nothing to gain” by gy camping. I beg to differ. It’s a strategy and prevents opposing players from getting back into battle.
