Because at the moment we dont have players from two servers squeezed into one.
And what CCCP suggested applies to farm maps too, it will be far more difficult to farm items & jewels at Lorencia, Noria and Devias from now on.
And in my opinion Blessed Arena is a terrible map, it should be taken out ASAP and its spots moved to the original maps where they belong, because lets face it.
Maps like Blessed Arena and Stadium makes players inactive and leveling up effortless, meanwhile maps like Crywolf, Barracks, Refuge remain empty. Peace!
