3v3 is dead.
The gamemode is full of bots, to the point that people start many games by asking "Are there any humans here?" Kinda boring. The gamemode itself is pretty fun if ya ask me, it could def use some balancing and modernizing but hey it's okay, just build a new game mode instead of fixing one of your old ones. Just let it get run over by bots until eventually you just delete it like you did dominion and the people who actually love the gamemode give up on the game. (Yes there are bigger problems than this in the game but damn it's annoying)
