Well it depends.
if you like dueling and want to go in the path of a fighter choose either the soldier or the dueler class, compare the bonuses and decide which do you prefer.
if you would rather help build your town by constructing buildings and just do jobs choose the worker class.
if you just want to travel the world and find items easier choose the adventurer class.
Craz, thanks for the post. Mind a follow-up? Dueling and adventuring sound fun, travel around, lots of variety, etc... Building, on the other hand, seems ... boring, from what I can gather so far. Does a builder just hang out in a town working on upgrading the towns buildings. So, log in, update a build que, occasionally spend skill points, and log back out? Are there other rewards for being a builder (beyond the class rewards)? I ask because I was leaning towards being a builder, as I see all kinds of town notices looking for builders, but if being one is little more then acting as a human bot to push building queues then perhaps I should reconsider. Thanks for any headsup you can offer.
