Just because you don't know how to use them doesn't mean the stats should be bumped up. If they are it'll become OP. Learn to use them and you won't have a problem.
If they get a buff the players who are already good with them will be completely unstoppable.

They are on par in most stats to a scout rifle, just inferior in shots, ammo, fire rate, and range. That's not a good thing. I expect them to dominate PvE and Iron Banner pretty well, but in straight PvP, they weren't good enough.
