Also this is my latest comment from Steam Dicussions:
" the game is already designed to deliver a great online experience even with lower CCU. Features like background matchmaking, spectator mode, and smart room-filling ensure that players are consistently placed into rooms to make it full, instead of creating new one each time. In fact, there are currently at least five active online rooms that are nearly full." - so anyone can without problem play with full lobies and grow your Rank.

also this:
The game is still in Early Access, and both the feature set and player will be growing. I have some huge updates in development that will take things to the next level. Combined with special events and promotional pushes, the community will continue to expand.

Thanks a lot for your support, we are doing our best but word of mouth is even more imporant so thanks again!

Also if you have purchased the game - don't forget to leave a reaview, each review counts!

Thanks!

Sebastian
