Basically what jimbob said. I used to do PLs on an SK back when Mortal Coil was deific. Basically you grab a non-weapon primary to avoid riposting, mass pull a zone that can't hurt you, have some form of AE aggro, have them use an Oil of Fennin Ro or a low level PBAE, then turn on your damage shield and have everything beat itself to death on you. In the era that Fangbreaker is in, a Bard with a healer and a mage or druid (or just the druid) would probably be the best choice. Nothing rips aggro off their PBAE Slow songs, and their DS songs stack with Mage/Druid DS, so they'd pull as much as they can, let the PBAE Slow song pulse a couple times, have the PLee use the Oil 1-2 times due to resists, then cast the DS on the Bard and have the bard start twisting their DS songs and let everything beat itself to death against the Bard.
When you can start grouping with them the Bard can just put you in group and charm kite for very quick XP as well.
