No, this is not another idea that will ruin the energy system, but its for the people that hate doing dungeons of its repetetivity.

Basicly, zones are gonna be like the first area you start it, Except much bigger. In order to go into an area, you have to pay 25 ME/10 CE to unlock it. Once you unlock it, you can get in and out of it freely. Whenever you die, you have to revive the samw way inside the normal dungeons, and there will be quests in there. But please no " KILL X ANIMALZ" or " GET X ITEMS". They should be based around a plot to expand the lore of this game. Lets face it: Without lore, this games a bit bland.

Towards the end of a single player zone, there will be a big event boss that people can form a group just like regular dungeons. The only diffrence, is that when you die, if you dont have enough to revive, you have to get out with 0 ME. No one else can revive you.

I hope OOO does something like this in the future, because spiralknights needs a bit of a thing to do on the side.
