You don't need more to give, you need to give more of what you got

A quote that's helped me a lot in life and seems like a pretty relevant ideology to adopt for this game.

You don't need better teammates, you and your teammates need to enable each other to give more of what you got.

More often than not your shitty teammate is probably struggling to be enabled to play to their best.

Is that your fault? Maybe, maybe not.
Is that your problem? Yes, so try to help.

Help your team give more of what they got and you'll win more games!

of course there are notable exceptions
