Ex6tenz is the French Pronax. He is horrendous at fragging and the most overrated IGL in his respective scene. There's a reason why he's always been in the 3rd seed French team, a reason that HLTV and reddit fanboys can't seem to see but is obvious to anyone outside of the general horde mentality.
His leading style is no longer viable in tier 1/2 counterstrike as you now need to be both talented at the game and great at your role. Ex6 is only talented at his role (IGL), but he cannot frag even if his life depended on it.
