TL;DR: PUGs don't reflect skill level and shouldn't be taken at face value, this being your first season on medic you are bound to learn a ton especially with someone as good as Screwball mentoring you. However, expecting high open without having any high open contacts, being known amongst the high open scene (due to not pugging with them), and not having any significant experience you are going to be let down and your medic attitude will consume you as it did me 3 years ago

Hey man just wanted to let you know that i've been in just about the same exact scenario as you when I moved to ESEA and if this is your attitude you will not have a good time.
I was a steel soldier in UGC for a number of seasons in 6s and 4s and decided to move up to ESEA on medic because of the stigma that "because medic doesn't have to aim its easy to be high open on and i can make playoffs fast and get good quick." I switched to medic and started getting high open/low IM players to ring me for scrims (I am VERY sorry to those who endured my aids medic play during season 20) or demo review with me. (also huge shoutouts to marmaloo and apex predator for putting up with me back then)
Like you, I was also under the premonition that I was better than I was because the players around me were bad and medic can't protect himself like the other classes (save for maybe demo but thats a different discussion) and blamed my team in pugs and TF2Centers (back before the drama when it was the cool place to play tf2 off of scrims and inhouses).
This attitude is VERY BAD. This WILL lead to you developing an ego, you WILL become a tilter, and you WILL become a toxic piece of shit. It took me 4 seasons of ESEA to step back, reevaluate, and realize the issue. Learn from my (and other medics before me, im not the first medic to ego out when their teammates were equally as inexperienced but had to both aim and think) experiences and pitch yourself as a low-mid open player.
If people are praising you in pugs or whatever that's great and a good sign that you have potential on medic but don't let that praise get to your head, especially if that praise is not coming from players that are at the skill level they are claiming you should play at. Try to be realistic with yourself. "Have I played with other players who are generally considered high open?" "If Yes, have i performed well?" If the answer is no, you are turning into S22 me and that is not good.
I wish for the best for you and I hope you have a breakout performance in ESEA (especially with ScrewB, dude knows how to play medic for real) but considering you are a steel soldier with no medic or esea experience you will need to learn stupidly quick and/or grind mechanics hard and get god movement/bows really fast to stand a chance amongst the other playoff medics.
