I'm not a bad player, but Ranked...
...highly challenging in lower tiers, and not because if my lack of skills. It feels like no matter how well you play, unless you can 1v5 100% of the time, you'll lose the majority of your games with practically anybody on your team. Solo queue is more difficult than it should be. It takes 10 wins in a row to be grouped with players who actually know the basics of playing and winning, but one loss and you're grouped with the bottom of the barrel. What's up with that?
Update: I went straight from S2 to S5. Yup, this matchmaking is amazing, right?
, farmed well and outscaled my opponents and just let my team carry me with their damage.
