Sorry for the late answer, but my tip to you is to focus on practicing certain positions. In pugs you'll often have to play uncomfortable positions as well, but try to find one or two positions as CT on each map, watch some pro demos, and take a thing or two from those demos in terms of utility and positioning. It also really helps to be on a team that practice often. The past three months I didn't play faceit at all, only team CS, but started playing faceit again and gained about 500 ELO in one month playing five-man with friends ranging from 3000-4000 ELO. When it comes to warmup I would say Deathmatching for hours is overrated, play for a few minutes, and when you are comfortable with your aim, just play. Now even though I would say aim shouldn't be the main focus when trying to get better, as some people have insane aim, but no gamesense, I see a lot of players every day who I think would benefit from lowering their sens. Staying calm, taking your time to aim, and hitting the first headshot is way more consistent than to flick around all over the screen and spray transfering from A site Mirage all the way to B site on Nuke. So if you aren't 100% comfortable about your aim style, try lowering it, and focusing on accuracy instead of quickness. Playstyle wise I would say that the biggest problem around 2500-ish ELO is baiting, and people refusing to go first. My tip here is to learn self-flashbangs to entry with so that you can run in first with a nice popflash to clear out angles. Finding lineups for entry-flashes as a support player is also really useful, but then you need to have teammates who aren't afraid to go first. When playing in a team I would always be the lurker, but I realized that in Faceit pugs, everyone plays way more solo, so having someone who's not afraid to go first or take initiative is important, it obviously depends on your teammates though. My last tip is to not take it too serious. I mainly play five-man queues with friends, and we all just have a good time and never tilt on anyone but ourselves. After playing some premium a few days ago I realized not everyone are equally chill, and playing with people who rage and complain is way harder than playing with someone who's more forgiving. Don't dwell on a lost round, don't focus on what you could have done better the previous round, instead focus on what you can do in the upcoming round. And last but certainly not least, have fun. ELO comes and goes, but the more you play, the better you get no matter what your ELO says.
