spear pure int nukers suck at pvp.
go s/s thats my advice.
usually you cant get a build thats good at everything, but good at certain things.
xbows pure str are good all around

go cleric subclass as well imo
glaviers and bows are good all round builds too (if you get to 90 or even 100, kb like crazy)
uhh... warlocks are ok too, all around build
s/s nukers will allow you to get a quick experience of the game but you may or may not like them
