That is not what i said. I said they needed one, as in at the time of the lineup was being built. But right now its fine, and you cant complain with the results atm.
If i need to give an example of what can happen when you dont have a proper igl, just look at ence. A few other examples: Faze after karrigan got kicked, G2 when shox igled, fnatic, nip, vitality without alex. There are probably many more throughout csgo, and cs history where having an igl for the most part improves structure.
This isnt to say that niko is terrible at igling, but that it would be better for him to be just a star player. In many ways he and shox share that characteristic.
