As I understand it one of the optimizations to allow the server to handle 7k+ people is limiting the range/sight that other players load. This is understandably necessary, and frankly its pretty amazing that the server does handle so many people so well.
I was wondering if it would effect server performance to turn these optimizations off for battlegrounds?
Battlegrounds are arguably the only place it really becomes necessary to see your enemies at a distance. It's really strange not being able to see a battle taking place in the AV fields when you're running along the outskirts, or not being able to see people at blacksmith if you're sitting up at lumber mill.
It seems to me that the subset of zones/players currently in a battleground would be fairly small.
