Bro you realize the game has only evolved, it's not like we are moving backwards. Every team in the top 10 is running the same strats just to different levels of execution at different times. You really think Fnatic of 2015 could stop a cat execute with the 3 smokes used now and the 7-8 flashes staggered at the awper ramp. Astralis nearly perfected counter strike and now everyone copies them. The nuke upper execute with mollies on hut and smokes mini heaven and perfect flashes, inferno A execute with smokes to isolate the player pit and perfect flashes for players going out halls. Fnatic 2015 have literally never seen those executes and would have no idea how to stop them, all t sides would be a whitewash. Liquid (and pretty much any team in the top 10 of 2019) would dominate fnatic, not to mention they also outskill them in every way. Olof 2015 is not as good as Elige is now, and it's not even close. You need to think about the game in a much more logical sense, Fnatic was the better team for that time, the best team of 2015 and nobody can take that away, but they wouldn't stand a chance against Liquid, 4 years of the game evolving make it so.
