I wouldn't take them out of the tier 1 group yet. They consistently beat tier 2 teams but they're close to falling into that tier 2 group. People view the different tiers in different ways anyway. Personally I think the tier 1 teams are in the top 6-7 90% of the time (sometimes falling below when worse teams have good runs). For example, BIG is ranked #6 because of recent results but I wouldn't call them a tier 1 team. Same with NRG. So it kind of skews the rankings of the teams a bit. I'd say Tier 1 ends with Fnatic at the bottom of it with MiBR; Mouz, Liquid, and Faze constantly switching around in the middle, and Astralis and NaVi at the top. This'll change soon I think NaVi and FaZe will switch spots so NaVi, Liquid, and Mouz will be in the middle of the tier 1 group.
