I like the idea of changing dynamis...

I could see them making it like abyssea in the sense that you get a limited time each day to go in with.. maybe say an hour..

no zone reservations.. everybody goes into the same zone and the mobs are distributed to where you don't get like 50 at a time. (wall of death in xarc >:U)

All the mobs would respawn fast so you could farm relic gear or coins w/o worrying about other groups there..

Maybe farm attestation nm's for KI's to force pop dynamis lord or something along those lines for zone wins.
