Don't stop moving, stick to the shadows, and take them down from behind. :spotted owl:
Don't give them any hints damn it!!! Don't forget I'm our clans sniper!
Also, I love how everyone is saying "I'll just run up to the sniper and blast him" or "I'll just shoot him in the face with my assault rifle" but those are slightly invalid tactics considering 1. He's a sniper, thus he's out of your line of sight so how the hell are you just going to magically aim and shoot him and B. If you DO see him, you will have less range than him so the likelyness of you shooting him is less than him shooting you. I mean I'm not saying you can't do it, but you guys are making it sound easier than it really is.
I also love how you guys are going, "Thr maps are close-quarters anyways so snipers aren't as useful". But how would you guys know when you have only seen bits and pieces of the maps. And some of the maps I saw had nice long corridors, some nice scaffolding, and some open areas where a sniper can keep an eye on the objective and pop people trying to complete it.
