Name wise it shouldn't be as bad hopefully since they did do their best to swiftly close access to character creation to the destination worlds. Overall though it will be curious to see how things play out with this. They are attempting to divert the population increase with the changes being made to abyssea though odds are there may be more changes to be made later on. Perhaps "Enhanced Playability" refers to balancing the way content is atm. One ne main issue that will probably surface is the increased difficulty in obtaining Empyreans in the merged worlds, while they have added more +1 +2 areas they haven't really made any mention of the items needed for Empyrean.

One simple idea is if they continue with their "Battlefield status" that they are introducing with dynamis and Voidwalker,

"Battling boss NMs:

* Battles will be conducted in Confrontation format, with a maximum of 18 players able to participate.
*Confrontation: A unique battle format in which the combatants are isolated from all non-alliance players and monsters for the duration of the battle."

If congestion with Abyssean mobs did become a problem I would imagine they could implement a system like this into the NMs that drop loot needed to upgrade the Empyrean weapons. While you may wonder why not just add more ??? to spawn more then one at a time, an imbalance issue that could come from that would be a group hoarding all the ??? and then brewing the 3 NMs at once or something like that lol.

If Confrontation works in the manner it sounds like it would work, it could become a viable way to create duplicates of the same NM so when it comes to bigger pop ??? it helps to lower the amount of time one will need to wait to fight the pop NM they desire.
