Best team ever is Golden 5 or Navi.
87-0 is still unbroken so NiP (even if I don't like this team very much).
NiP since 2001 nothing else
Hard to compare a team which didnt have so much competition , for me SK is the best team , since the money are much higher in the business and there is much more competition + SK is only 1 major away from reaching Fnatic.
SK DOMINETED 2016 AND IS DOMINATING 2017
of course its fnatic
teams were more motivated and were on a higher level in general, most relevant lan wins after NiP, most majors, best top 4 streak
