We need to spectate game, with a delay like 2mn. It is very very important for the community, cause a game is very stressfull and it is commun to look at your friends having some difficulties to get some rest. We can share the emotion about win or loose or skilled plays.
Spectate a game is necessary to create a good community and don’t hesitate to allow obervers to talk together about the game.
An other very important thing is to just click on friends to join a custom game. It is actually very very annoying to try to join the same game with friends, and if u enter a lobby, the chat disapears !
Try to separate the chat and the lobby if you can, and allow players to enter easier in the custom game.
