what about 2 int + 1 noob vs 4 noobs? I am somewhere semi-noob/intermediate, so It feels appropriate.

So 1 team can be 1 intermediate(host), one semi(me), and one more new player. this should offset the early game advantage that the 4 player team has.(and it feels a bit tematic with the name Our team can be team "Good, Bad and Ugly in one" vs team "just Ugly")
Also I am happy with a 3v3 game.
Let me know what you guys think.
