I mean I liked it because it probably explains why you can get different variations of rulesets and handicap with automatch.
If you have no preference say, and someone else does but they meet your rank requirements then I assume it probably matches you up.
I don’t think the automatch matches with the custom challenges.
Edit: @teapoweredrobot already linked the same thread
It doesn’t seem to say that’s how it worked when it was introduced
but maybe that might give an insight into some wait times.
