To anyone who wants to climb in Ranked:
My greatest tip for you: it is to know that the grass is never greener in higher ranks. You still get afks, people who do not communicate, and others who perform with a lower purpose.
I have been in diamond promos once, seven platinum 1 promos, and a couple platinum 2 promos. It is really a roller-coaster ride in ranked. One thing I think is important to know is that you're not the driver, just along for the ride.
Now, I am not going to say you can't make a difference, but instead, do not be frustrated as I have been when you can not.
