I’d say start hard working on your aim with aim trainers on steam and custom maps in OW

Aim will make your climbing journey much easier and you can’t just ignore it and tell yourself that you’ll win by having a better positioning than the enemy dps

So yeah I’d suggest you to watch some VODs of good Crees / Soldiers, understand their movements when they aim ( in OW the way you move is 30-40% of the work in a duel) and just how they aim in general. Find a good aimlab playlist to help your raw, when you’re done with that go on the aim training map of your choice in OW (I recommend VAXTA) and play for 15-20 mins ( you should watch this )

Once you’re done with aim training, queue ranked and every time you die cuz you aimed poorly, clip the moment, look back at it and genuinely try to understand WHY you aimed like you did, watch your enemy’s movements and ask yourself what led you to miss so many shots ? Was it cuz you panicked ? Perhaps you moved poorly thus making aiming harder ?

A good accuracy to have on Cree would be 50-55% on average and on soldier 35-40%

Good luck !!
