I think that tournament placing aint a good reflection of how good the teams are because there is so many factors you need to take in account. Like look at how fnatic plays today compared to when they met Liquid, it a huge difference. If liquid had met todays fnatic roles might have been changed.
And I rank Liquid so high because I think that when all teams play their best, only Astralis will beat Liquid. They are just in a slump RN because of everyone is beating everyone, alot of tournaments attended and so on.
