The map isnt very accurare regarding placement of enemy players who have been spotted by your team. When you round a corner and get killed, this is because the player who killed you wasnt spotted.
This is the other problem I've came across that bugs me. I've seen players appear on the map and as I get close to them, the orange triangle just vanishes. The same goes for when I've spotted someone. I've chased people through the woods/rocks and while they were shown on the road, soon as they went on the grass they had vanished off the map while I was still chasing them.
I've been killed too many times for silly things like this that I did not know. Solely been relying on the mini map until they were close enough. I'd then scan normally. Even when enlarging the map. Sometimes they were too far away and went another route. By that time I lost track of them but they got me. Yet they still didn't show up. It's sporadic.
Sometimes looking at the mini map with 38 players plus, I could have sworn I was playing on an empty server at times.
