Astralis/TSM, G2/Envyus, Faze, Fnatic atleast for EU teams. (atleast 35 big events together, 7/11 majors to EU) and those were only from events from beginning of 2015
Liquid five events within three months. C9 major
Luminosity six event success in 2016 (3x 2nd, 3x 1st)
SK two event success (right after the transmission from Luminosity) and year after that seven event success (6x 1st, 1x 2nd) also two majors together
Compared to Astralis: (23x 1st, 9x 2nd) *with under the name Astralis, TSM isnt counted there*
Overall success is a lot better on EU, I agree with the Liquid era but imo it was only few months, as Astralis´ era was for about a year and with the older roster, it was about the same lenght than Liquid´s era. Fnatic, G2, Faze, Mousesports have been good compenters for the whole time, and I would say that all of them had atleast some kind of eras, as Liquid was the only one for NA scene.
And about Finland, I didnt mention anything about it, but as part of European countries they are also count there as well as Italy, Greece, Serbia, Austria, Switzerland, even your Malta is relevant as to count in.
