I think it could be argued that hes goat IGL after winning the major, not only international.
I know what u gonna say, gla1ve 4 majors, but he had the perfect team (for 3 of them) which clicked perfectly, now watch him stuggle with new astralis, which is never gonna reach anywhere near the level of old astralis. On the other hand, karrigan made work every team he has ever been on (at least for certain period of time). TSM were decent at the time, reached several finals, won some tournaments and were n 1 on HLTV for quite some time. His first time in FaZe I dont need to mention and his time in Mouz... well, that was bit more of a struggle, but still won 2 tier 1 tournaments. I'd like to see glaive to do that and I dont think he could.
