Ok,so I would like to suggest the 'pre-ready up' system,you join a lobby,and you can go afk,play a pub...It's way better than this 'WHO IZ NOT READY' system ;) my opinion ...Let me know what do you think!

The main idea behind "ready system" prevent AFK players joining the game. If we'll allow everybody to join freely, there is a great possibility that someone will be AFK when the lobby starts. Our system isn't ideal and we continue to figure out the best method to filter AFK players. We leaves your idea here and we'll see how much votes it will collect.
UPDATE
We're looking to implement a short pre-ready-up. Basically being able to ready up whenever, but it will expire after a few (3-5) minutes. It will allow people freedom to leave their machine / not sit watching, but also ensure that when game starts they should be around.
Update:
Short Pre-Ready up system implemented.
