I just started only like level 5, so my opinion is much more theoretical than practical. So far so good, having experienced nothing other than killing mobs in the newbie yard of nektulos. Exp is slower than THJ but faster than Quarm. Have gotten a few of the other class AA skillbooks and some of the upgrade currency (fragments) off newbie mobs and those things sell for 1-3k (while costs to turn in the items for AA are like 300pp) so its not hard to get started. i've only sold the upgrade things not the AA skillbooks figure ill need them.
You can port to the guildhall and back from lvl 1 with the free AA, port to your bind point, and /bazaar from anywhere.
my initial thought was since everyone gets every skill then skillcaps is what matters, so roll Monk. But then I remembered how gay 15lb max weight is, so Warrior!
But then I wondered how AAs that cost mana work on classes without mana, and so I ultimately rolled SK.
So far it seems SKs AA books are the most expensive since everyone wants the tap AAs so prolly SK isn't a popular / meta choice for your base class, but at least i'll save money not having to buy AA books i can just learn the AAs with exp.
