It wasn't highly successful to me as I was lured and died many times losing Noble armor which was good I think at that time (PS of course I agree with it coming back)
I just want to add on my opinion to Hyper's suggestion about PvP:
A long time ago in an old survival map there was a PvP arena built for people to use. It was highly successful. Just used world guard allow PvP in that section of the map. It was a drop in style like Kit-PvP was. If you didn't want to participate in PvP you never went there. If you wanted to indulge in that, then you could. Simple as that. Giving the option in Survival was great. Anyone who wants to bring up the argument of 'what if people don't want to lose their items?' Well, there's a very simple answer to that. Don't bring anything to the PvP arena you wouldn't want to lose.
So this is a great suggestion from Hyper, in fact I agree with most of Hyper's post.
