Few questions on farming - Nightfall/Prophecies

With a warrior, i see that many skills for farming come from proph and i only got factions, does nightfall have anything similar for replacement?

What about other professions?

It's really hard to answer this question
When you have Faction and Nightfall, you'll miss some skills from Prophecies
When you have Prophecies and Factions, you'll still be missing some other skills from Nightfall

Just invest some money to get the whole set.....
