Create a 3 vs 3 mode death-match map. Give that mode x2 pvp xp so people can get to rank10. The biggest issues, once players hit 80, get melte down by rank10's they quit the game.
3v3 map will give more mini games, give players a fast track to pvp gear and it will also create more intimate and fun pvp mini experiences,
You have nothing to lose at this point.
