Please note: I here want to focus on efficiency - maximum honor per time unit, not the best way to win AV.

How to properly do AV?

AV weekend starting today in EU.. grindtastic.
So what do you think is the best way for a 5-boxer to play AV? Since 5-boxers have quite an impact on the battle in AV, I'd like to know what kind of playing style will give me the most honor per time unit in AV. I'm running an S3 geared 70 hunter along with my 4x 68-69 shamans.

Full PvE offense?
Full PvP offense?
Dynamic defense?
Zerg?
Something else?
