players from americas are mentally tired as fuck after giving their lives to qualify for masters. EG as the underdog had the least amount of pressure from the public, NRG and Loud HAD to perform.
EMEA teams had an easy life (much weaker teams, you cant argue that any team that finished below NAVI is good enough outside of EMEA.) fnatic literally didnt had to use tactics at all, Liquid had to try a little and NAVI who had to put their lives out there also got burnt out.
LOUD, NRG (they wont make far into this tournament if they keep this form) and NAVI are coming back much stronger at champions after this break and mental reset.
