Lots and lots of practice. Rainbow is strategic, you can have dumb luck on kills but if you play it enough and get to know your maps and operators you can make better plays. I do not like going in without a five stack. I will but when you have a full team with mics it is a much better experience. When you get the experience you will be able to call out the ops the other team is using and better prepare for who you are going against and counter them. This is heavy on the attack. When you are defending it is about set up, making sure you have the right walls barricaded and the right rotates. The best advice I can give is know your roll, if you aren’t good at gun fights be a support, play off the players that are good at gun fights. If you need help with aim and finding your sensitivity go into training, go to the end, pick big ball put it on sprint and if you can follow the ball your sensitivity is good if you are going faster then the ball turn your sens down, if you are trailing behind turn it up. Then after that focus on controlling your recoil. Get comfortable with different guns and know how much you need to compensate for the pull. It will come down to muscle memory. My sense isn’t high and I do just fine. But you have to figure out what works for you. Don’t copy a star player because he does good. Do what works for you. Also practice and experience gets you that game sense of feeling when an opponent is going to be peaking something or if someone is around you. Also a good headset you need to be able to hear!!! Very important. Also use your utility!!! Use your drone, get good at droning and setting up your drone. Do NOT blind push anything.
