Will this get me to Plat?
Current Silver 3 here and the highest I've ever been is Silver 1. I have been playing since Season 1. I don't think I have lasted more than a solid 5 months before I just don't feel like playing one day and then quit for 5 or so months. Now this last break I decided to go hard at Starcraft 2, now if any of you have truly played that game then you'll know the learning curve is crazy high. The mentality I developed because of Sc2 and the purpose of this question, is "Take something away from each game" win or lose as long as I learned something new, I was happy. Back to League and I failed my promos horribly and started at Silver 5 but am up to Silver 3 about 2 weeks later with a 70% win rate for 16W 4L playing purely Support. I have not raged a single game, I start every champ select trying to get everyone's lanes figured out and my signature phrase of "I say this in champ select so I don't know how you'll do, but if you start to lose lane please play as so and get wards and pots, we'll help you out" This get's a positive response about 90% of the time although I doubt that will fly so well past Silver.
So to sum it all up, will having the mentality of "Take something away from each game" get me to Plat or higher if I truly do follow that or is it deeper than that?
