These fixes are great. Adding the 5 person queue option was a great addition as well. The current state of AV is horrendous, and i'm glad they realized that it needed to be fixed.
Notice me using the word fix, not change, because ranking in AV was never a thing in vanilla, so this is not a change, more of a fix.
I only hope this moves the rankers into WSG, but we'll see on that.
