Vitality were a much better team than NaVi 2018-2020. While they didn't have more individual skill, they had much better teamplay and veterans in that regard. s1mple had to carry egregious mistakes that even with electronic he couldn't fix. It was much harder and the peak was much higher for s1mple in 2018 than for ZywOo in 2019. They were similar, yes, but all the clutches, entries, awping etc. you described apply for s1mple in 2018 and even on a higher level. Plus it was during the peak of the Astralis era and Liquid being consistently the second-best team in the world. Much harder than 2019.
