That incredible run shot him up from being perhaps a top thirty player of all time, to a strong candidate to be called the greatest ever.
And it's actually ridiculous to say 'top thirty' prior to 2018. He was easily top 5 even before his four GSL wins. Greatest proleague player of (arguably all time) SC2. OSL, SSL, WESG and consistently high placement in GSL, even in the era when he and innovation were the only ones even qualifying for GSL. I bet if you went back to December 2017 and asked players to rank each other 1-10, Maru would be on 100% of the lists.
Otherwise nice write-up.
