as a 4k support main I found qp games with silver friends extremely frustrating due to the extreme chaos and lack of structure (normally devolving to team deathmatch)
the tanks don't know what they're doing (e.g. rein charging on cooldown, sniper dva feeding, etc)
the DPS don't know what they're doing (mccree going for cheeky flanks and dying most of the time/getting a single pick)
the other support doesn't know what they're doing (wandering off alone to duel people)
adjusting your playstyle works, so as a support you become super aggressive, the enemy makes near constant mistakes and you pounce on them immediately
vs. a GM game where everyone knows what their role is and the game plays much more "normally", and I can't get away with that sort of behaviour
Ended up creating a new account, ended up in high plat and quickly became diamond, never to drop lower again.
Why/how did this happen? I'm not sure, but ELO hell was real for me.
