SMG and AR users noob... that's rich. I would say no more than 10% of the random "snipers" I have run with or into are even capable of breaking even much less going positive. If more adept at route and board management this wouldn't be a big deal.
Second, I am not a sniper but have tried out QS a number of times to see if I had the "mystery" skills. I must be a QS savant. The last time, post patch to see impact or effect, I threw an 18-2 round together with a Ballista. If I can do that, somebody who uses the weapon class regularly needs to let their pelotas drop and grab some or the simple truth is they are not that good.
Or keep crying a river...
