phobiasky_1 rly fast and easy tip for you silvers to immediately get to at least nova 2, stop aiming at the floor. Watched 2 minutes of dreamboat's stream last night and remembered how bad new players are at aiming head or even chest level.
i aim at head i just dont know how to peak corners
knowing how to jiggle peak or strafe fast by a corner when going for a shot will slowly become muscle memory just gotta get used to the maps, play dm more it helps your reaction time a ton as well as aiming. getting used to the recoil, control spraying with certain rifles etc
movement/aiming mechanics are very important like any other fps game it will become better over time when you play more and slowly learn the game. but one thing you should take note of when you start ranking up. being able to understand the calls (assuming your team isn't mutes/trolls) knowing all the names of spots. and knowing smokes/flashes...this will become key. watch youtube vids for certain maps and practice them it will help a ton
