It would be nice if you could set up a match that consists of 3 or 5 games so you can play an opponent more than once. Weather I win or lose I always accept rematch where most people only ask for rematch when they lose and as soon as they win they move on.
I personally enjoy a grudge match where you play multiple times and try and get the better winning record.
This is actually an interesting idea. It seems like it’s doable, where they could make a best of three or best of five “arena” and you could choose your desired time within that arena. Seems like fun, hopefully they can find a way to make this happen in the future.
