So people have been asking for something new for PVP and they want small group PVP but not the 3 way fight we currently have in battlegrounds.
So my suggestion would be group dueling. It would be the exact same as individual dueling but with groups. The only stipulation would be the groups have to be the same size. Additionally, this should be an easy thing to implement. No new maps to create. No new gear to create. Just have to put in the code to allow two groups to duel.
So basically the group leader of one group will invite the group leader of another group of the same size to a group duel. Then the two groups go at it. I also think resurrection should be allowed because the duel would just turn into each side focuses one player until eventually there is a two on one scenario. And, I also believe that keeping the other team from being able to res is a necessary part of the game. Now of course that could lead to a really long fight so there should also be a timer and the side with the most kills wins.
