''xizt made nip win a major and tons of finals''
No, the fact that they had the best players in the world made them win a major and tons of tournaments. If you're going to give the IGL 100% of the praise for a team winning then you're actually delusional, especially when it comes to a loose IGL like xizt. xizt is a good IGL when playing with some of the best talents in the world who can play loose, if he doesn't have that then he can barely be considered an IGL. Look what happened to NiP once GTR and f0rest dropped form, did they continue winning thanks to xizt's great tactics and gameplan as an IGL? No, they became irrelevant and eventually kicked him. pronax winning majors and titles also obviously relied on playing with some of the best individuals in the world (olof, flusha, krimz) but atleast he was a solid IGL with solid tactics and a gameplan aswell as having great mid round calls.
