The trouble is, Alterac Valley still gives the highest Honor-per-hour which makes it the ideal farming ground. Ironically, you can get high Honor returns without ever having to kill a single opponent. That's just fundamentally wrong. The size of the Battleground is such that it allows players to achieve the map's goals (capture of towers, graveyards, etc.) while bypassing one another completely. It has become a flaw of the game design that high Honor is gained with expediency.
Disturbingly, Zarhym over at the forums has stated that Blizzard feels that Alterac Valley is "well-tuned at the moment". This means we're unlikely to see a fix soon, if ever. While I'm conceptually against players killing for the sake of killing, such as fighting on the roads in Arathi Basin, Honorable Kills need to be more integrated with the map's goal. Perhaps towers can be scaled with the number of player deaths. What's important is to actually bring the 'battle' back into the Battleground.
I have a feeling Blizzard is relying on PvP Achievements to fix the situation. Unfortunately, it's an external fix and doesn't address the problems with the map itself. That also means that the fix will be months away. Until then, Alterac Valley will ironically be a largely PvP-sparse zone where you can and will end up with less Honorable Kills than, say, Arathi Basin. I just hope that despite their thoughts of it being "well-tuned", developers are aware of how combat needs to be intergrated into zone goals. Otherwise, a zone like Lake Wintergrasp might see no PvP at all. And that would be a tragedy. So... how was your Battleground Holiday?
