@Lord_Scorpion34 I haven't used it often, but after getting shot at it from afar a bunch of times (and after watching idiot teammates peek a team with triple 30-30s and get downed immediately after), it's pretty good! Really nice weapon for putting pressure on the enemy.
I think its real disadvantages lie in player skill rather than innate mechanics. If you can't hit anything with it, obviously you're not helping your team. If it's your primary weapon, you have to know how to play at close-medium ranges so that you're not so far away that you can't support your team if they push, and not so close that you're trying to duel shotguns / Volts / R99s with it.
What's really annoying however, is that since it's super new and no one has ever really needed to learn how to play close-mid range, (in my matches at least) everyone's just sitting around poking each other constantly at the 70-150+ meter range. Then you get a knock, or someone on your team gets knocked, and you gotta ask the question of, "How the heck do I push this?" Chances are, 90% of the time the answer is going to be, "I can't push this, they're too far away / there isn't enough cover / hey look another squad poking us from 70-150+ meters away."
