You're full of shit my dude. Before summer rain wasn't what he was now, of course, everyone knows that. However, he performed well all year. He was a 100% pure entry before the summer, his role was extremely tough, his rate of success was insanely high at the time, but the task he was given was somewhat alike to TACO, yet he actually managed to find success.
Even at that time he had his insane performances at Starseries, IEM Sydney, etc.. he was a top 15 or top 10 player in the first half of 2017 and in the second half he's holding a top 1 spot, only one who can contend it is really NiKo or Coldzera. Having that much of a performance is insane and should easily be top 5 in the year if he continues his performance for ECS and EPL finals.
