What is Rank ?

Yo Rito, why I go 8/2 in Provisionals and get B1 when I was S5 last season? Is J4 at fault? Is there any particular direction you can guide me in to understand this madness and if so, there yet? I just wanna get it, cuz I don't. I went 8 for 2, man. 8 and 2. I'm not LCS Photo yet but I suppose for my rank it's pretty impressive, and I only had at max 3 matches with KDA's below zero. How I was gifted this is beyond me. I at the thought of it. Aight now I'm just bein' a tryhard, but it ain't easy bein' me, nnnn ? Holla at cha boy Rito. ~
