Ex6TenZ last had a good team in 2015 basically, as his stay in G2 was so short.
If you would have given him the same tools as Happy has had, he would 100% achieve much more. He is a brilliant IGL, but he doesn't have the trust or authority to lead players like shox or NBK.
Give him RpK, kioShiMa and ScreaM and he'll make a team that is twice as good as nV.
EDIT: Hell he even has almost as good of a team in LDLC, and he has 1/10 of the skill to utilize.
