Maybe this is ridiculous, but a one click "Every fighter challenge all" button. Currently I can click a fighter, then click fight, then click Challenge all, repeat 20 times. Seems like it's not a big deal until you're crunched for time or you're trying to do it from your cell phone. Or I can click one button on the Team page and be done. If you're too busy, log in, click the button and BAM!!!!!...instant increased "activity" for all to benefit from.
It has to create a record for every challenge so it's not some easy thing where you can do mass challenges instantly so what we got now is close to how good it's going to get but as far an auto scheduler option...that can appease the busy / lazy people a bit more as an opt-in option that you can check on or off and fights will be put together and fought automatically for you. You'll just need to set your styles, unless the division is bare and there are no active opponents for you.
