your faze and mouz points are completely incorrect
- FaZe roster was a top 15, bottom top 10 at best before he joined, the roster had 1/5th of the faze that became a top 3 team. rain jkaem kio fox and aizy. After he joined they skyrocketed of the rankings, and within half a year they were solid top 10-7, he then saved NiKo from Mouz, and got the team to top 3. After he got olof and guardian to make the "superteam". One misconception though in my opinion, was the real skill level of that team, sure rain and NiKo were amazing, but they only really shined under karrigans leadership. Olof was not that great, bottom top 20. GuardiaN was very inconsistent, high skill ceiling yes, but low lows. His system is what allowed that team to thrive, and you could see at their height that his system allowed for rain and NiKo to have some of the best performances of their careers, and GuardiaN had a decent resurgence after lackluster performances in NaVi.
- Mouz should be his last real top tier team i agree, but it was NOT completely built when he joined. In many interviews (his reflections with thorin is a good one for this), when he was contacted, it seemed like he would be playing with oskar sunny ropz and another player. But oskar and sunny abandoned the project. He handpicked the players after, he chose to keep ropz, bring back chrisj, take a chance on frozen, and get woxic from hellraisers. In the beginning they didn't do that well, but once the team got comfortable, and they switched frozen's roles, once again his system allowed for ropz to have a massive spike in performance, massive spike in woxic, and frozen.
Are you completely forgetting the fact that they made 5 finals in a row and won 4 of them? sure they werent all tier ones. But they were showing a very high level. This event should be a one-off for them, very disapointing yes. But 100T are known to do this kind of thing, upset tons of teams and sneak into playoffs. The mouz roster is young, and Rejin (coach) is working very close with karrigan, you also have to consider on all his other teams, they didn't have very good coaches for most of the time. RobbaN didn't do shit other than tell them they could do it. Zonic came in way to late for astralis for karrigan and him to really have a good working relationship. And rejin is a very good coach and analytic.
Also, with astralis, FetiSh was a really average IGL, that team was bottom top 7, top 4 at best, players weren't that exciting, only dupreeh and Xyp were worth watching at the time, and karrigan killed their choker mentality in 2015 for many events, especially vs fnatic, turned device into one of the brightest stars of the new era, and yes after Cluj the team platued and fell off, but the entire time they didn't have a coach, or any real infrastructre. People forget that even with gla1ve, astralis was in the exact same position in 2017 as they were in 2016 with karrigan.
