This is a good time to jump in the game if you haven't already.
Beware the level of crankiness in the game, though.
Almost every single game starts out with at least one person being hostile and pissed off. If it doesn't start immediately, it will start after the first time someone gets killed or someone doesn't doesn't buy a chicken or wards, meet at the rune or doesn't do a creep pull or even just makes some other random mistake.
So be prepared, you just gotta shake off the trolls and you will find some enjoyable games. It is best just to ignore them and not even talk to them.
