Have you ever wondered why in Multi-day and Real time sections, the autogames(1v1 or 2v2) fills faster than the games we host?

nope :(
it's obvious, nothing to wonder :)

Is it because of easy wins from auto-games?

It's because it's a know template were you don't have to worry about the settings.

yeah sometimes people do retarded settings like 20% offensive kill rate 80% defensive kill rate, so just playing a well-known template with generally liked settings can be easier for lots of folk

also blacklist don't apply on the auto-games

Always wondered, why there is no rule to "avoid blacklist for this game". For example blacklist seem not to matter in 1v1 games, but makes hell lot of a difference in team-games and FFA. Maybe something like that gets added in Unity. Would like to avoid blacklist in my 1v1 games.
