God no! Please please PLEASE NO. Being able to only see the players within 5 meters of you is one of the worst things gw2 had. It is so immersion breaking to only see people who are right next to you. If there are problems with monsters being invisible then maybe your computer isn't able to handle the game well. I play on a 4 year old laptop and can only run low-medium settings and I've never had this problem. The way gw2 handled this was absolutely terrible and no game should ever reproduce it. Hell I'd take 5 fps and serious server lag over not being able to see things, it is a cheap and terrible way to fix a problem.
