Flusha if motivated can do it all, he showed that in periods in Fnatic as igl and aswell in Cloud9 .
I could also take gobb instead of ropz, but i truly think that would make it worse, because ropz is to important in that lineup. He is so stable, and dont take that much space. Thats why cold and flusha fits so well, because they can adapt to any roll, and leave Xantares and Zywoo to be the stars. Ropz is that stable player that is not only great in most aspects of the game, but also super important in making great decisions in hard positions , plus amazing pistol player.
