SE, Please just instance fight encounters

[Jennestia]

I also know I'm not the only person who would love to play an MMO version of FFXII. You are correct though, FFXII was the only final fantasy with non-instanced fights.

FFXII was built on XI's foundation as they felt they could have always done more with it so it was the "true vision" of what they had for XI, so the online FFXII = FFXI, just not set in Ivalice. The Guildleve system in XIV is already basically pseudo instanced as it's open world and the monsters that are yours/your part will only be interacted by such.
