Very insightful and truly helpful comment. I know how to play the game above a decent level. If I didn't, I wouldn't be where I am now. I still have a lot to learn, I won't deny that. But, at the same time, it's very obvious when you have crap teams and bad games. Let me tell you the difference between a smurf and a player actively trying to climb:
It's hard to actually climb after sinking 200+ games getting to where you are. While smurfing, your MMR is so high, that eventually, you'll end up matched with higher tier players even in lower tiers. When this happens, you get better and more decent teammates. Because of this, you can climb more easily (on top of getting that oh so lovely LP and division skips) so smurfs don't exactly go through the hardships people trying to climb out certain divisions go through. Granted, that's not to say that they CAN'T climb, but surely they won't climb nearly as fast as from a freshly created account.
So, no, this is not a L2P or git gud case. It's a toss up because I don't play adc. And when I do play adc, I get camped and my team ignores my lane. I don't get peel and I don't get to play the standard that actually wins the game. When I play top, my adcs are actually garbage. Even if I DO peel for them, they can't position to save their lives. When I play jg, all my laners feed and can't actively set up the lanes to be ganked so I'm stuck trying to counter jg for people that can't word or position. Actively, I think my performance, for the most part, is pretty consistent. Obviously, consistent enough to hit promos 7 times and finally succeed on my 8th time.
So yeah... you can can your much "needed" suggestion.
