This is my 4th build so far and I have had some trouble with this build to be honest. I ended up with Sentry and Hunters Faith because they both work hand and hand together with the extra head shot damage and better acc and stability. This build is a one shot killer but its a good tactical sniper build. You can hang in the back and cover your teammates.
In the video I was using Recon Pulse but later switched to smart cover and I like smart cover especially in a team play because somebody will have a pulse or you can use the pulse talent as a backup. Overall to me great build can be better will work on it. Great starting point.
Hope you guys enjoy the build and video.
