As you level, the profit gets better and better.
At first, you won't be getting too many blues and penya, but it reaches the best point at Kings and Mams, but Kings really are the best.
It is easily possible to make 200M in a few hours at Kings with a party.
Mams aren't too bad either.
So yeah, try to train on Kings whenever you can, even if the exp is horrible.
If you manage to get a nice Ranerz, you can start to Aoe kings as early as 97.(That was in V12 though) Ah, makes me think, back in V12, aoeing was so easy as a ranger, with the 0's from suit elementing.
I could tank the whole Kings spawn at 98, but then, v13 messed up everything.
Anyway, you'll be making some money in Azria for sure, but it only gets really good at Kings~Mams.
