Competitive Discord

The official CF Discord has a section called e-sports however it’s pretty dead.

The closest thing to an active competitive Discord is CPL’s Discord which is is ofc about CPL (a weekly competitive cup for all regions).
There are however LF team, LF scrim etc. channels in there, which you can use regardless of whether you participate in CPL or not.
