@Slowrider7: That's true, which is why I see a lot of people get frustrated when they leave them in rooms. The trick is to put them on an elevated position that takes time to reach, is hard to flank, and where it can see over any cover. Placing it near an enemy spawn in objective matches will also wield a lot of kills.
