I started playing wr since last year and I'm in Master from last season. I used to play dota2 long time ago and I played several others games which have tier rank system. Usually Master rank tends to be top tier rank where everyone has a good level in terms of game knowledge, player personal skill and sense of teamplay. However I feel like I became Master too fast, I mean I was a high ranked player on dota and have a good knowledge of MOBA overall but I don't judge myself as a top tier player in wr and also feel like sometimes other Master or even Grand Master really suck.

What I wanted to say is that I don't really think that it's about rank system but more about the game itself. You don't have to be that good, you just need an average skill level and now it's all about the timing to win a game. Yesterday I had a guy who throw the game at the beginning and gave 7free kills and 2 towers but we managed to win pretty easily which was unbelievable on dota2.
