Things I did: Escaped ELO hell.
How to:
1. Play in a position where you can easily assist your team with frequent ganks(jungle=prime).
2. Barring that, play what your team requires. If you have to play support a couple games tough it out. That being said, don’t always play the meta. A ranged ad carry could use a bruiser with a hard stun(who’s willing to not sacrifice cs) just as much as they could use infrequent heals. The late game importance of a support Amumu is much greater than a late game support Soraka, say.
3. Never surrender. Farm beats kills every time, wait it out if your team is in a bad position. If you’ve got some really bad players, everyone gets better with items.
4. Play jungle ad Sion. Do it. Oh and don’t listen when you’re team tells you not to get Sheen. Trinity-Atma’s-Wit’s End.
5. Teamwork and helping your team out is key.
