Not defending Thorin, just explaining why he has this bias.
Despite not winning a major, Karrigan will go down as one of the all time greats as he's brought 3 teams to the top and is great at getting teams started up. No other in game leader has had so many teams at the top, only Zeus is close with 2 teams (and Gambit was more of a fluke with players all peaking simultaneously). After Karrigan and Zeus, i can't recall any IGL's taking multiple teams to the top (Don't count FalleN, it's just different orgs then ruining new careers)
Kicked from Astralis due to differing ideas on team identity/ style. More of a mutual kick.
Kicked from faze because NiKo is an ego machine and the players lost faith in him after boston.
Hopefully not gonna be kicked from mous :/
This new Astralis is nothing like the old one, it's not even worth making a comparison. For all intents and purposes, it's an entirely different team as they lost their IGL and support player who are arguably the 2 most important players.
The old Astralis is characterised by Glaive, Xyp, and Device. You could replace Magisk and Dupreeh with any 2 good riflers and as soon as the communication/ teamplay is tight, it'd be pretty much the same team.
Karrigan has taken 3 different teams to the top from scratch, no other IGL has done that.
Astralis comparison isn't fair because this new Astralis is essentially an entirely different team.
