Proximity Mine queues seems to be insufficient

One common theme I have noticed in my rather liberal use of proximity mines is that everyone I play with has run into them at least once. Though this might be a skill issue, I suspect that players who have not seen them before are not aware enough with the current green blinking light and tick audio represents something that can hurt them. My suggestion would be to possibly make the blinking light red or possibly beep increasingly violently as players get closer to their arming range, or some other indicator to represent danger more obviously.
