Is there an advantage to being in Windia versus Scania versus Bellocan... etc. I chose Scania for my first character but that was because I didn't really know which one was the best one.
Any thoughts?

Basically each server is different. New Servers have a Very unsteady market & they are very hard to get to really high lvs due to no one being funded. Popular servers are CROWDED Hard to get into PQ although easy to find parties and a very steady market. It all depends what you prefer.

Scania and bera has cheap items but it is extremely crowded, therefore, lagging you.
Khaini, the one i play, is not so crowded, and people are nicer compared to windia and bera, but Khaini has its reputation of hackers and the scrolls keep skyrocketing -.-
If your new i recommend Bellocan or Kradia, bellocanists are nice and not everybody is rich, so is kradia.

It's true .
