Lets start with the EXP - You lose 1% for dying in PVE. And I think this doesn't apply in the early levels (like up to 10? not 100% sure). It also doesn't apply in Kingdom Quest.

with PVP you only lose EXP if you died in a map called Abyss, and u'll lose 0.1%. If you died in PVP Kingdom Quest you don't lose any EXP. If my memory is correct, you don't lose EXP in Free Battle Zone either.

In Fiesta, generally Mages and Fighters are good PVP class. Mages have lot of debuff type of skills and fighters usually have a large HP pool and high dmg. (Of coz, you'll need to reach certain levels to get all your useful skills..)

Archers and clerics are weaker in terms of PVP. That's not to say you can't be a good PVPer with these classes, just that you'll need lots of cash shop items...

IMO archers are good solo PVE class with its kiting skills.
