Honestly I don't think the real issue here is the grinders... I think is the fact that there are just too many choices... spread canta pvpers between 6+ maps and pvp much much harder to get... especially if you then add nummy little tasties that only one faction can eat all over the maps to ensure spreading the pvpers out. Cap the zones, not to protect grinders so much as to narrow down where 80s can go... get them down to 1-2 maps other then boss battle, and I bet pvp pick up fast. In Ep4 was some Dwater pvp, some dinos, some DD1 (more rarely DD2)... now from 3 maps went to Dinos, DD1, Dwater, VR, PR, KI, the 2 new grinding maps, and canyon of greed... 9 maps for lvl 80s to hide from each other and look for nubs to kill in *smiles*
