Let's face it, most people want PvP but also want town safety. The biggest reason no guild accepts war decs is because one guild can grief the crap out of the other anywhere with no repercussions. So why not add another type of war dec, or change the current war dec to where you can still go criminal for attacking eachother, but now players cannot report the murder or cause standing loss. This way, guilds can kill eachother while still having some kind of safety in towns.
