I have this issue where I care a lot about how I perform in ranked, especially when it comes to solo q. I don't really care if I'm winning or losing, but if I'm playing bad I feel like I'm letting the team (of randoms) down. And that they're gonna flame me. Does anyone have tips about this?

I think this is the biggest reason why I don't play ranked that much, but I really wanna reach ascendant this act. Oh yeah also any tips for using the mic if I'm really uncomfortable using it?
