I'm really really really frustrated by my situation. I started last season jumping directly from gold 5 to plat 1, then i lost 4 promos to diamond in a row and got stuck in plat 1 forever.

In season 6 the story is the same, I kept bouncing between plat 1 and plat 2 forever but now i can't win. I just can't.

For whatever reason, I always feel like i'm playing 1vs5. So i tell myself that I have to carry but, even trying as much as i can, I achieve nothing.

All KDAs on my most played champions are very good but Gragas/Kha'Zix winrates are atrocious and Elise/Rek'Sai winrates fell to below 50% after a 60 % start at the beginning of the season with all four picks. Also my total winrate fell to 48% after a 56% start.

I really need help finding out what i do wrong. Since I don't like afk farming junglers, I always gank early, often getting kills too. My farm is not bad and I try to keep my level as close to solo lanes as possible.
