Come on in. So, how's your tripwire business going? No luck? Figures. This isn't like mindlessly shooting everyone. You've got to have a sense of intuition and know where the prey's gonna be. If you were a hunter, you'd understand.
Try watching where the bandits hang out. Think about where your wire would catch the bastard off guard and how to conceal it. Take your time, use your best judgment.
Only then will your hunt be fruitful. Come back when you find at least a couple good spots. I wouldn't be so quick to set these tripwires around, otherwise you'll kill some of your teammates by accident.
