What's the point of Omega Ruins?

[rubah]

It's an easier place to level up than the Monster Arena,

hmmm, not if u kno the trick with the master tonberry. thats easily capable of giving u 99 sphere levels after the battle, and isn't even a difficult battle.

Okay, so what I meant was 'the fiends are easier to kill to level up, so that by the time you kill them without immediately fear of death, your magus sisters *might* be tough enough to kill earth eater without dying much'
