I would recommend using NLB on control, rift, and salvage since those playlists usually contain mid to long range maps. Also, aiming at someone's head triggers a red dot just above the bar within the scope, same with PVE. This tells you where the shot is going to hit. It ONLY works if your sights are on the head though. The gun is challenging to use but I have a blast using it from time to time, even though I miss about 90% of my shots in PVP:). Just play around with it and you'll eventually gain progress. Practice makes perfect. Hope this helps.
