Since 4.0.1, for whatever reason, Blizzard has increased the radius at which players get honorable kills AND because of how the new honor system works, individual kills count more for honor than they did before.
What we're going to do here is to utilize the Honorable Defender buff you get (50% more honor) and use the knowledge that we have a larger radius in which to gain honorable kills to our advantage.
Step 1: Capture the Blacksmith (ideally this will work with any node in AB or EOTS, but the BS is by far the most effective)
Step 2: Stand right by the flag at BS and look at Farm - about 100-200 yards before the flag is the maximum radius that you have to receive honorable kills. Park your butt there and make sure you have the buff.
Step 3: If you see PVP activity (for example if your team is zerging Stables), then move closer towards Stables while still staying in range of the Honorable Defender buff, so your "HK radius" encompasses more territory, thus resulting in more kills.
As of right now, I've made about 30 honor just typing this post - this method is great for multi-tasking as well.
