Some think that having dominant team or two means that rest of the region is weak. That's how it has always been in EMEA. Fnatic and FPX owned EMEA last year, but did that make teams like Guild, Liquid, G2(fluke), M3C weak globally? No it didn't they were still Masters playoffs level teams. While NA outside of OpTic and at times XSET/The Guard were just beating each other left and right and did that make the region stronger than EMEA? No it didn't. Having bunch of B tier teams beating each other doesn't mean shit when they have to face those S tier teams. Top half EMEA teams last year and before were way more consistent regionally compared to NA for example while teams like LOUD were just farming their weaker regions.
Fnatic didn't lose a single map in Lock In only dropping 2 after going 2-0 up in the finals(winning vs LOUD Ascent as well). You really think this team wouldn't be undeafeated in any region when even LOUD managed to do that until last game?
Fnatic is the best team before proven otherwise while NaVi would be competitive and possibly even favored in some against LOUD, C9 and NRG. Any Americas team outside of those 3 are completely beatable by other top half EMEA teams. Teams like Giants, Liquid etc wouldn't be underdogs vs EG, 100T, FURIA type teams.
