idk if it's just me, but I think it would make sense if someone no-shows or whatever..count it as a no-show
don't replace people because replacing someone can cause someone else to lose, when they should have won their assigned match
That's just my opinion.
and before someone says "Well it's been like that for a while" or "It's been like that since the start" it's not too late to change it, specially if a lot of people feel the same way.
