I suggest an addon to duel
1. Where the player can send Duel request to another just like trading req, and of the other accepts, they can duel anywhere.
some guys might spam battle requests too and its not gonna help if somebody is hunting something, etc. so i support you that it will become difficult if the staff makes it available everywhere
i agree with iplaymaker its a good idea maybe battle request could teleport u 2 battle hall and then when poke faints itll port u back 2 ur previous location!u could also block people from requesting battles because trucid said about spamming!
