Only own Factions: Whats worth farming, and what to use?

Hey dudes, i've had GW:F for maybe a month and a half now, and it absolutely rocks. But all I find when i look up farming guides is for anything other than Fac., or uses skills from other add-on's. What is worth farming in GW:F, and what is a build to use for farming using only GW:F skills? thanks !

Doesn't the classic Vengeful ritualist build work with Factions-only skills?

assassin/ele with shadow form and sliver armor

search it using search tool

Great thanks for the replies... but what areas are good money makers?

The ritualist build was introduced for the vermin outside Senji's Corner. (Take the X. Skyway exit and generally bear left.)

The E/A build is meant to hunt bosses for their green drops. There are lists around.

The rit build can probably also clear Jade Armor and Am Fah on the various streets of Kaineng. It's extremely versatile.

One note on the ritualist build -- its classical form uses both Ancestral Visage and its Prophecies twin Sympathetic Visage. So without Prophecies you may need to use it where adrenaline/energy denial isn't crucial.
