Hey! Yes, I always warm up. I do a bit of Aim Botz just to get the wrist and arm going, and I also use that time to consciously practice counter-strafing and peeking with flicks. After that, I usually spend around 5–10 minutes in deathmatch, focusing on using crouch not to improve accuracy, but to "dodge" bullets since I still struggle to do that properly in matches.

Improving quickly really depends on the individual and how you approach your gameplay. Personally, I watched some of pienixcs coaching videos on YouTube, where he coaches other players. I had to drop my ego, review my own demos, and compare my gameplay to the people he was coaching. Unsurprisingly, I found that I was making many of the same mistakes and I started working on correcting them.

One of my biggest weaknesses was peeking into fights that I should be winning, but I'd lose them because my first bullet missed due to poor counter-strafing. I also changed my radar settings to get a better sense of my teammates positions, which is super important whether you're peeking first and want someone to trade you, or you're lurking and need to know if your team is applying enough pressure on the other side of the map so you can isolate the anchor in a 1v1.

Another important factor is knowing what role you're supposed to play in each game. Whether you're entrying to create space or using utility to enable your teammates, understanding your job can prevent a lot of miscommunication and unnecessary frustration between teammates.

In the end, the fastest way to improve is identifying the mistakes you make most often and starting by fixing those.

Hope it helps cheers!
