I dunno. Being a mage outside of abyssea really sucks. Sitting on my bum waiting for MP is boring.
I think we should simply add a new astral fighting ground. Where you do 0 damage if you have no MP, and get a constant 10 MP per tick drain while engaged. That means all melee jobs need to gear up in MP gear to deliver damage. It will be so hilarious to watch them try and manage MP and then cry "This sucks!".

Or better yet. A zone with constant "no cures allowed". So that melee have to go sit and rest HP. Oh how fun and "challenging" it would be. Please add this SE. All the melee want a challenge like this. I swear on my level 1 PLD.
