It may not seem much to some, but...
... I did it. I hit Plat 5. I started of this season in Silver 5, and after 12 ranked Games I stopped completely playing Ranked until the middle of September. In 2 weeks I got from Silver 5 to Gold 5 by one tricking Mordekaiser. I stopped again, but some weeks later I started playing ranked again, and hit Plat 5 in a week by doing the same things. I know that there are ppl out there, to which this is nothing, but to me it's something very special. This also shows that you don't need to pick Meta champions to climb, you can also pick off meta champs and benefit from their strengths. It may be a bit different, but it is worth it.
Have a nice day!
