I’m afraid of the unforseen consequences of adding such an instanced instant pvp action arena for the rest of the EVE universe.
I’ve seen it happen in World of Warcraft where instanced battlegrounds reduced the amount of fights happening in the game world outside those battlegrounds. I’ve seen it happen in Runescape where the ‘duel anywhere’ option was the final straw for the fun fights at the duel arena.
Additions like these are not just nice additions. They also take something away.
In EVE I’m afraid it might take part of the liveliness out of the rest of the universe when the people who are looking for 1v1 fights aren’t encouraged to participate in that universe anymore.
