Why Starcraft II is not dead?

It usually takes me like about a minute of less to find a team for 4v4 but, I am usually matched with people in many different leagues.

Is it that fast? I remember taking 4 to 6 minutes back in 2019 to find a 3v3 match in the platinum MMR range (stopped playing since then), I assumed it got worse

I did, however, used to find reasonably even matches

But which game can be called strategy game then? Chess is about memory too. Even the best chess player Magnus Karlsen in the video where he passes the test of end games keeps saying: Oh, I know where it is from, it’s Kasparov game, you win it like that! He is not creating moves out of the head, but chooses moves he has seen, read about, played before. If chess is not a strategy game, which game is a strategy then?

Maybe in 3v3 the system tries harder to match people of a similar league. If the system was setup so that players had to get matched with only those in their league, 4v4 would be talking a long time. Especially for higher ranked players.

I think the reason is because the MMR I played is a middle range MMR, so I guess that’s where most players are situated, with more players the chances of getting even matches are higher

People in the extreme low and extreme high MMRs must have a hard time in team games
