Idea B.)
CAMPAIGN!, why has this large battle system gone completely unused? It it because the battles aren't fun? No, not at all. Its because in the hour you fought fighting Nho'mo Crimsonarmor, you only got 1-3k XP. The xp awards for things such as besieged and campaign haven't been properly adjusted, as normal xp mobs have been.

I propose the Campaign/Besieged XP values be multiplied fivefold, to keep up with the increases of normal xp/abyssea xp.
