quick grinding area...., for the mid-30's

i'm a summoner(lv32 ATM) and wanted to kno the best place to grind where i can get levels fast in the shortest amount of time. i found that killing asron's and echidna's proved to be a quick way of leveling, but i think that will become obsolete in the next couple levels. any help?

EDIT:also, off topic is there a level 32 quest given by Lucas in Requies Beach? i havent been able to find him, but i kno the quest thing told me it was there...
