Farming luxon faction?

Is there a place/quest to farm luxon faction fast? (FFF) as easily and fast as kurzick faction?

to quote from http://guildwars.wikia.com/wiki/FFF

Quote: 1. Leave Jade Flats (Luxon) to the northwest. Have runner run to Arena Master Portus and complete The Jade Arena quest, /resign and restart. Proficient teams finish the run in around 1.5 minutes, making it ~475 Luxon Faction per 1.5 minute run. At around 10k faction per 40 minutes, this is currently the fastest known Luxon Fast Faction Farming.
the Quest "The Jade Arena" is the fastest way that I know of

There's a Luxon HFFF guide here in the farming forum. It's slower and more complicated than Kurzick HFFF, so i have to agree with Ambuu.

Just outside the luxon fort aspenwood gate there's 3 yeti bosses(4 if you have a quest active) and a ton of regular yetis and rot wallows. It's possible to kill 25 of the wallows and regular yetis then kill the bosses for 250 each in about 10 minutes or less. I was in HM messing around with H&H and it was 9 minutes when I had killed the last yeti boss, I bet a full ursan team or something with SoJ could wipe em a lot faster. This gets you a over 1k a run per player, plus drops.

If you don't feel like getting a group and do HFFF from Jade, you can also do it from Breaker Hollows with henchies.
