I wouldn't say it can die when i'm playing, and the sensor is good WHEN it's working. I also thought i'd be fine without changing the dpi, but as i said it can randomly change dpi. For example i'm gaming at 2000 and suddenly it changes itself to like 400, despite still showing it is at 2000, then i have to bump it upto 4000dpi, and after that that it'll stutter for about 30sec. This occurs both when using a cloth and hard mousepad, aswell as just using it on a wooden desk.
