Lol you have very little concept of what it takes to get a kill as a gunslinger. Tripmines are completely avoidable, i am rarely killed by one. If you ever played as a gunslinger you might have some insight as how to avoid getting killed by them. And if you are skilled (i don't check stats, you play as well as you play, i don't care) and have absolutely no problem avoiding tripmines, then you should be able to reach the logical conclusion that tripmines never gave you free kills, if your enemy had any skill you have always had to work for a tripmine 1 shot.
