Is it possible to Turn Diadem into a zone instead of instance?

[silentwindfr]

but how are the developers supposed to balance the complex mechanics if they can't control the enviroment like they do in instances? yoshi said, any encounter mechanics need to be ballanced and if it's in open world then it's gona be impossible to tune the encounter! plus if its not instanced then it's not final fantasy right?

simply no, the encounter in the diadem are simply monster with tons of hp, it's a zone put into instancefor force group.
the trouble is diadem is a junk. people don't want to partake into this sort of boring grind without interest.
