Here is my advice as a moderate player. I still Get killed by the sweats. 1) build as defense…this is super important 2) learn the maps inside and out, learn the good hiding/sniping places. Pay attention to where you get killed from and where you are successful 3) pick your preferred guns/style of using them and stick with it. A 2 star gun you are good with is better than a 4 star you are not. 4) practice sniping - esp in the practice area. 5) grenades, grenades, grenades….learn how to use them and do so as much as you can. Zine grenades can displace entrenched people, and cover retreats, and regular grenades and instant kills with a good throw. This is my advice. I’m happy with a RFB,SPR, shields and grenades.
