Expand dueling radius option
I've talked to many people who would appreciate having a larger dueling area as an option.
During the "Accept or Decline" menu of a duel challenge, the radius could be mutually agreed upon as a preliminary option. If there wasn't unanimous agreement to the size, then the original size would be the default.
The option to increase radius could also be capped to something reasonable to prevent exploitation.
Even 50% more radius would be massively appreciated as an option.
