The most Faction per hour?

As you can see, or already know:

It takes 10,000,000 (10 million) faction per character to obtain maximum rank in the related skills.

As Kurzick or Luxon, what is the most faction per hour that you have obtained and what do you do to farm it?

Both the Luxon and Kurzick factions have "arena battles" you can play over and over to get 400 faction per run. I've gotten it down to 6 min runs with all henchies but then again I don't have everything customized. A dedicated "faction run" with several players can rack up to 20K an hour, although I average 5-6 K on my own.

The other good way to rack up points is wait for double faction weekends. Dedicate the faction to your alliance and you're essentially making quadruple points.

Personally, I find AB to be the most "fun" way of making faction but it can be interminably slow and frustrating. I average 5K if we're winning a lot, less if I can't find a good team.
