Strength of team at worlds

I just hate to see how everyone exaggerate result of every match. For example: first week GRF loses to G2 and everyone starts saying they are bad, now that tables have turned and GRF won 2 matches in a row, G2 are bad. Everyone is also saying how good is SKT and how bad FNC looks.. just wait, everything can change and I woudn't be surprised to see 3 tiebreakers in group C. There are many more examples (FPX=LGD assumption after first match).

Please don't make opinions about team, based on couple of matches !
