Key to progressing in ranked silver

When I reached gold last season I came to the relevation that I was grouping with potatoes in mid for apparently NO REASON at all, just staring at each other unable to initiate for like 3 mins. I remember having lot of Malphs which won't initiate because "he has the upper hand and pressure". Baffling isn't it?

This is real typical in silver and making your move quickly is one of the prime keys of getting out of this place. Manage your side lanes and make it push towards them, Kill em all if one is splitting and run down the turrets fast. If you are support get a siege item and place it on top to get free swag towers. Be creative and decisive.

play and watch people kill themselves on you

I feel like it takes too many games to move up. I have 59% winrate in my main role (22 games), 50% in my off role (2 games), clearly I should be rated higher than I am, and I'm moving up, but it takes so many games.
