Well, you have to die in order to get better. You can't just avoid dying totally. Even players like Dom and Moon who are experienced players die from a base defender while raiding. What i recommend doing to get better with recoil and such is get your firearms level up so you can craft your own weapons. When you have your own weapons go and raid. Also always try to remember that you will lose a lot of weapons and get tickets. Otherwise you can train recoil outside of the game in an aim trainer like kovaaK.
