Key is practice practice practice. With both those weapon type you want to be hitting heads so work out heights specifically of peek corners as if you miss that initial headshot you could fall prey to a good scout/pulse user. Same for HCs without those headshots most decent primary's will melt a hc body shooter. I run Nature of the beast every now and then and by hitting heads will often beat even 600 auto users, as alot of them just spray the body. Key is movement, don't stand still even when sniping unless you find you are playing against poor players that always take the same route. Know the head heights of sniping lanes and ambush where possible. I find with something like Jade rabbit or Graviton Lance if I get the first shot in 8ish/10 times I'll beat the sniper. So be wary a half decent scout/pulse will still be challenging. Most of all don't be predictable constantly camping the same spot will lead to being flanked or a good opponent will peek shoot you as they know where you are. Good luck fellow Guardian
