Contrary to popular belief BEFORE the update, the TTK is extremely low, being 0.83 seconds if all shots hit the target directly. Now, that's easy to do once you get in the sights of an enemy, but 1.you need to be pin-point accurate and 2.getting that long snipe is NOT going to happen. Adding on the somewhat mediocre coverage, and you get a bullet hose, easy killer, but easy to get killed.
A weapon like this is the Last Word in Destiny. You can win 1v1s with ease, but 1v2s is hard. It's better in team play, but I think it's going to grow into a competitive favorite. Can't wait to see it grow!
