I can only see a small advantage to PV on smaller maps like Haven.
However, I use my radar rather well. I rarely have a problem distinguishing which direction an opponent is moving. I'm also pretty good at predicting in-game behavior. Most of the players will do the same things over and over again. --- "Opinions should be a result of a thought, not a substitute for it." http://i.imgur.com/FwBee.jpg | http://i.imgur.com/nfZQy.jpg
