Hey guys, I was watching bleach episode 190 and I heard about Espadas. That reminded me about this game. I wondered, I'm currently downloading it right now but when I start will anyone help me?

I have 2 questions, Which 3 classes are best at surviving and leveling and money making? ( don't give a damn about pvp)
Which server has the most Onrpg people?

+ If you can help me advicefully and financially maybe then can you please post which server you play and your IGN.
