"Also if you think Liquid with taco was a failed lineup you're delusional. Literally the most successful NA lineup of all time and if it werent for Astralis would have been one of the most successful lineups ever."
We are talking here about THE MOST IMPORTANT condition that will lead a team to success. Liquid target was to beat Astralis and dethrone their domination while becoming the number one team in the world. As you know, they failed in this regard so the primary objective wasn't accomplish whatsoever and as a result Team Liquid failed with their plan. Even though they were the second best team in the world and the most successful NA team ever, they failed to reach the desired spot despite the fact that this team's lineup was created to bring the team to the number one spot.
You're presenting BiG here as a team that had the strategy but lacked individual skill which is true, but remember thay you've choose an edged case. Many teams have / had their lineup into an equilibrium zone that served raw skill, supportive players, igl's and tactics, but lacked the most important think that leads a team to a dominant success. I'm talking about the hard overwork that only Astralis managed to master and accomplish.
