Yo, this is from the POV of a roamer main who only pugs so take it with a pinch of salt.
Took a quick look at your logs.
Your scattergun accuracy is consistently around 60-80% which is pretty decent. (Don’t think it’s a problem with your aim.)
Your K/D is pretty bad for a scout. You seem to be dying too much and you take really little heals.
Maybe it’s a problem with communication? You may not be relaying enough info to your team / playing off damage or comms from the others / asking for enough heals / etc.
There’s no need to push for an aggressive playstyle if you’re uncomfortable with it, it’s better for you to play a style that keeps you alive and a threat to bombers than one where you try to force your way through a choke, do 5 dmg and feed. (Don’t bait your team for stats though :3)
About the stress, the only real way to counter that is to try and think positive. We all make mistakes and sometimes whiff shots we shouldn’t have, it’s just how it is. Keep practicing and someday you’ll grow that confidence.
It’s a videogame, GLHF :)
