Plat III now, but not sure if I'm good enough to get diamond without luck :/ I'm getting carried a lot. I mean last game I went 8/0/10 as Cait but it was mostly my team spoonfeeding me kills and me not doing anything outrageously stupid. I didn't really make any plays.
If I go mid or top I almost always go even or lose lane. Jungle varies a lot. Botlane also varies a lot.
