Matchmaking really took the community side of the game.
There are still communities but they are much more localized. It is probably better to look inside your country, and if you are american, inside your state.
Add people that you consider cool, with time you will get a grip of a nice hand of people where you can have a symbiotic relationship and grow together
Matchmaking, faceit, cevo and ESEA are the community based events i'd say.
GL and hope to see your clips here soon
