Very interesting.  I usually get 25-30% more honor than the estimated amount.  I rarely kill the same person more that once per day (unless they're stupid and continually target me.)  I also solo (or close to it) about 25% of my kills. The rest is random DoT spamming everything within range (including hunter pets, pisses them off to no end)  I also killed a treant for the sole purpose of regenerating mana through spirit tap...but I'm strange like that sometimes.   

I also soloed the Arch Druid in AV (he REALLY hates getting silenced)(Died 4 timed in the attempt (intentionally due to oom+low health), but it was quite entertaining) because everyone else was focusing on the allies for their HKs.
