So to start I come from overwatch, a fast paced moba shooter that doesn't involve very much time just holding an angle. There have been many a time that if I'm holding an angle for more than 20 seconds and I know they are still there from sova darts I accidentally zone out or something and they swing I my not ready for it. The only way I keep myself engaged is by having my eyes glued on the minimap. Is there any strategy anybody uses to stay alert when holding an angle?
