Why no more quests?

Im doing nightfall campaign, ive done all the quests i could find at the moment in all the towns i could find (the digsite one being the last i could find without running past lvl 15 mobs)

I am currently lvl 8, but i cannot find no more quests anywhere, unless theres a town i have missed somewhere?
Or do i have to grind from lvl 8 to lvl 12 or first sunspear? >.< which would suck since i hate grinding exp.

You probably missed a mission in one of the towns. The person will have a green ball on top of their heads, instead of an arrow, indicating its a mission. And in NF you don't have to grind for levels at all, the storyline runs very smoothly IMO (compared to prophecies storyline, which i found very jarring).

Those are all the outposts, including mission areas. Do a bit more searching, and you can find all the quests in Istan as well. For instance, there is a bunch of quests out in Zehlon Reach in the Northwest.

If you're having trouble getting your rank up, make sure you get all the bounties while you are out questing as well.

These guys offer bounties to kill certain creatures for Sunspear points.

If you've done all the quests you can find but don't easily meet the requirements for those types of quests it's likely that you haven't been picking up the bounties from the Sunspear Scouts (they stand at the rez shrines). If you've done all the missions available to you and need to do that quests next, it looks like you'll have to farm some SS points until you get the rank you need. It's only 300 points so you should have a bit of that done already.

Thanks for all your help, yeh i found some quests, had to kill a lvl 24 for one, as a lvl 9 :P still do it np though got first spear rank, so im on the quests again thanks.
