A refreshing change to old difficulties.... thoughts?

If its a quality of life update. The two most obvious things to change would be as many mentioned having to refresh arena battles 20000 times before the opponent you were trying to find finally appears and secondly for the love of god give us Mod Presets that could be switched with one button. As much as i enjoy spending hours remoding toons one mod at a time (thats was sarcasm, if someone didn't catch that), it's about bloody time they made this a thing of the past.
