The hardest thing about Solo Q is Recommendation.
You notice only the enemy Leblanc is fed, 14/2. She's the only thing stopping you from winning. So you tell your team it would be best to build on some MR, but then they all flame you for being a noob and build either fully armor or build no MR at all. It's insane how you communicate a good tactic and the entire team gets salty and flames you.
You insure your allies that baron isn't contestable, it's better to back and get ready to defend so push the lanes as is then recall. Nope... they all go in, not as a group, but one after the other follow-the-leader, and get one shot by the enemy Yasuo who is already 8/0.
But you can't group with anyone either cause' for some reason when you add microphones to the team, people get sooooo escalated about recommendations. I really can't find a solution for any of this anymore besides just... not talking at all.
