I agree with what Nick and Clare have said about players abusing it or players not wanting to be involved. You may say that people won't, but people will, or measures can be taken but it is always a greater inconvenience to those that do don't want it at all. A lot of people have been saying that they want more of a survival or real minecraft experience and then those same people suggest putting plugins into hardcore to protect stuff, which is fine and definitely a possibility but does not make sense to me. A normal real survival multiplayer experience would be no plugins and the idea of having plugins kind of goes against one of the main arguments for a more real and dangerous experience. Additionally, I do understand that a pvp arena is not the same kind of experience so maybe, after more discussion, a faction server could be added, however 'teams' and protected area is kind of not what normal vanilla survival multiplayer is. Cy11's suggestion for pvptoggle is something that does sound reasonable however and could possible be some kind of middle ground that could be implemented.
