I main Sona and Soraka in Silver, trying to get to gold. My winrate is above average on both, but I would like to up my game with some macro rather than just healing and supporting the team.
What else should I do?
How important is vision control?
What role do I have in mid/late game?
Should I roam at 15 minutes or so?
What really difference do I really make? It's hard to judge how much you do since you can't compare damage dealt.
