Lol those predictions though. Immortals above TSM and NRG? Dignitas better than Cloud 9? NRG better than C9? NA tiers are very clearly TSM=C9>NRG=IMT>TL imo. I guess the NRG and IMT are more guesses and can be off but you are overhyping Dignitas a LOT. TSM looks like it could be the best team NA has ever had atm, i hate TSM but they look damn good right now.
EU top 4 looks like OG>H2K>FNC>Vitality. Maybe FNC goes a spot up or a spot down, but other than that i wouldnt know. the 5th spot is a matter of opinion, idk Splyce or G2 well enough to decide.
If you want other people's predictions, here are a couple of articles that happened to almost exactly agree with me, so if im wrong at least im not the only one. http://www.goldper10.com/article/2939-nalcs-2016-spring-split-preseason-power-rankings.html
here is the EU version http://www.goldper10.com/article/2931-preseason-ranking-of-the-eu-teams-for-lcs-spring-2016.html
And here is Dyrus' opinion. https://www.facebook.com/TSMDYRUSLOL/posts/936716926397516
I would take that with a grain of salt though. Players tend to rate teams more about how they do in scrims than anything else, and the other guys who are putting up these rankings are being paid to do so. Players also tend to completely ignore how good a team is in the macro game, that's why you see Forgiven being rated so high despite his small ass champion pool.
