Is EG fluke 1 month team?

I used to be really high on them and consider them an S tier team but it seems to me they are flukers. NRG is def better than them

eg's lotus has always been bad and its also fnc's best map
series hasnt ended yet tho

they are best NA team rn but I feel like they wont keep consistent like NRG or LOUD

NRG is better than them based on what?
