Or the fact that the way the fight is done would completely change depending on where you fight him, which would require impossible balancing for the dev team. You may not know this, but terrain can drastically change a fight.

Example: 13 nails in ifrit extreme. However your are in a forest and the amount of space to spawn those nails at the right proportions would be impossible because there are trees taking their location. Then when you want to aoe 3 nails, your aoes can't hit all 3 because there is an obstacle from the open world that doesn't let you position yourself correctly.

Now this is just one problem that could happen and could easily be fixed if it were by itself, but there are countless possibilities for where the balance of the fight could be broken because of the terrain you fight him. The outcome of all this being constant bitching similar to the hate about the fight being instanced.

This is why you fight primals in a certain location and not in a random location at thanalan or the black shroud, because the terrain works well with each primal's mechanics.
