Scrims are matches between Clans (in this case GF Teams)
If 2 CSGO Teams Train against eachothers its called a scrim aswell
Yeah, I already knew that for like 6 years, thank you? That's how some people call a native pracc too, I'm not stupid. ^^ But Smylie mentioned a team ladder
which is entirely different to a scrim
Edit: Or do you mean the 'official' matches will be the ones accounting for a potential ladder? So on top of offering a matchmaking feature aka randomizing players on the moment, you also plan on offering a structure (with servers, match/stats tracking, etc..) for regular gf teams?
