Quests per Level?

Hi All - I am curious where are the best places to do quests to level up the quickest? I didn't know if there was a guide that once you hit a certain level range, it is best that you go to this general location.

For me about my 30's was spent in Fazenda where the quests were around 30k-100k and I gained about 10% per quest. Once I got in the 40's, I switched to Arcanois where the quests went from 100l-400k and again I gained 5-10% per quest. See where I am going?

I am lvl 48 now and stil in Arcanois. The enemies here are still pose a challend but the % gain is small (expected). Looking for a heads up where to travel for my 50's...

Youre gonna progressively move to Elephunc. Basically same as youve been doin, just quest as much as possible including bulletin board quests, do events, and invasions. You'll level quite a bit just from all that. So long as you get a lvl a day, youre doin great.
