Honestly I used to be trash with every sniper. I'm still not as good as most of thr people I've seen on the upper end of trials matches but I've gotten much better with a lot of practice. I've ran exclusively with the sniper in most matches to prepare for trials and it's actually helped a lot. I don't think the aim assist is at %1000 lol, just that people practice like crazy with it or are just that good at sniping.
