As always, I'll begin this by explaining that you can leave any comments and criticism in the Creative Discord where it is much easier for the Matchmaker Team to see what you write. If you want to join, you can find the link through the Official FAF Discord.
Otherwise, if you would rather state your mind on the forums, this is the thread to do that. Let loose.
Here are some old ladder links from the old forum:
