{Suggestion} Arena

In FF 7, you can battle against monsters in an Arean in the Gold Saucer area. I am just wondering if this would be possible to add in the Arena in FF11.

Benefits:
-Rare Equipment
-Rare Items
-Chance of getting a fully upgraded Relic/Mythic Weapon.
-Allow you to get 'eggs' to allow you to raise your stats by one point.
-Test just how well you do on your Main Job.
-*If you do well on the 'Fights' already in the Arena, you fight against yourself, testing your limits to the max, instead of fighting Maat. (Doppelganger so to speak.)
-Have this Arena allow you to raise your carrying capacity by going through many many battles. (Locker, Mog House, Sack, ect. Different kinds of Battles for each thing desired to raise capacity for. Example: Magic Battles - Locker.)
-Allow you to obtain a Weapon Skill of your choosing, only if said job with A+ skill is at maximum level. (SAM at max level, gets to choose said GK WS, ect.)
-Rare Synthesis Materials.
-Newly added Spells.
-After fighting many times, you will be allowed to have up to only 4 Party Members to compete in said battles. Adding only one member at a time, testing your bonds to each other.
-Gain Job Abilities/Traits.

Benefits will be bought by something similar to Cruor/Gil. But something different.

I know this is a long shot, but I wanted to add in my opinion. o.o
