i would recommend not playing AImlab! Aimlab is for showing off and trust me, you wont get better with "training" like that. the experience makes a FPS Player better. I don't know how you play or where the problem is but Ranking up is something that's not up to you only. I personally deranked a lot before a while and made it back to diamond/immortal. i got often mates who was drunk or on drugs and teamattacked us and called our positions to the enemies and this happened back to back over 5 games. i normally play duelists but to rank up i gave it up and played more kj, sage, omen, sova and raze. jett and phoenix are difficult somehow and i feel like you need support to play these guys well and in some comp ranks you cant get it. when i play with omen, i try to motivate my mates like the jett and offer them the flash so they can dash and get some blinded enemies. thats somehow important. if your jett or reyna plays solo without support (like i mentioned before) they will get bored, frustrated and suck. try to read people. try to remember what your mates did before in similar situations. work on some annoying stuff like use tricky walls, tricky turret. the key is some teamwork! dont get to greedy! most people ruin games because they dont know where to stop and fall back for the moment. the key to win games easy is to annoy the enemies as much as posssible! since i dont know your situation, i would also recommend taking a break and playing only deathmatch and spike rush for a while. back to back dm and sr. playing with a brain filled with question marks and old tilt is bad. free your mind, dont be rude to your mates. wining games was and is always a bit lottery in this game. just realize yourself your rank rn doesnt matter and nobody cares what it is rn. try to remove the rank pressure from your brain. in the end you should focus on getting better with your positionings, read, mindgames, crosshair placements, movement. also for me movement is more important than aim. if you have great movement, aiming will be much easier and this comes with experience!
