If you want the easiest path, go N/N herald, no real enemies and everyone wants to take you on PVE trips.
Once you get the hang of the class you'll find you can explore most all of Thera solo (and kill most NPCs so long as you are patient). You'll likely end up going on adventures to tougher areas with groups too, which can be useful for learning areas and such.
PVP you'll lack at kill sealing ability, but you can hold your own in most fights and if you're smart you'll know when to get out of fights and when to press for the win. Bash will be a nuisance sometimes, but that's about it.
