For new NRG to be better than previous, I'd assume that the igl would have to be close to FNS in terms of quality. Otherwise there's no way the team is so much better than a team like old NRG (optic core + s0m+ ardis) which nobody called a superteam. Only IGL close to FNS is saadhak and that would be crazy but I don't see LOUD breaking up except for aspas obviously. So the only options are 100t and g2(ex-guard). 100t could be an option if they're cooking up some crazy shit. G2 with leaf or aspas or yay is also a definite possibility.
