I would like to see the league creation method be changed slightly. I would like it to be similar to the character creation, where when you enter a name for a character, it checks to see if it is available/ valid and then you click on Finish. With the league you enter the name and if it is available it creates the league, but what if you want to check other names? You have to disband the league, wait 5 minutes I believe before you can check another name. I have also had a glitch happen where when I disbanded a league it said the league name was still taken when I tried using it on another toon right after. This was when wavedox.net was still up and running and it said my character was still part of that deleted league even though he was part of another league and that is why the name was still taken.
