Good supports for silver.

Hi everyone, I recently got into silver after climbing my way out of the depths knowns as bronze V...I tried loads of stuff but ended settling down as a support main as I seem to do a lot of work there. Anyways. I got out of Bronze using Rakan, having a pretty decent win rate, but as soon as a got into silver a few days ago, every game I've had has been a loss. Not just as Rakan, but as Janna as well. I mean, I can deal with an ADC who seems to have no clue what to do, I can work around that unless they're really bad and just int, but of course, cannot deal with the top or mid lane dropping themselves in an unescapable hole of feeding from playing stupidly aggressive (Which seems to be a curse down here, no one being able to play passive when losing and when I do it, I Get flame despite obviously just trying to hopefully wait for team to scale into late game). I'm trying to find some supports that can make a huge impact even when the other lanes feed or get behind. I can and have played most of them in the past in normal or something at some point. I'm thinking of picking up again, Of course I could always play but I tend to either hit everything or nothing on him so would prefer some consistency. I used to play a lot a few months back and did pretty well, usually as a counter to champs like etc, but his win rate is negative so I'm not sure, but as it was with despite being pretty good on him. So any decent suggestions for champs and builds would be appreciated. Thanks :) [slayer-jinx-catface]
