When BG’s come out (soon) you will be better off doing what it is that helps you WIN the BG.
Why?
Because farming HK’s is pointless in a BG, the bulk of your contribution points (points that convert to honor on Tuesday) are provided mostly by winning the BG.
Honor kills provide a very small portion of your standing in BG play.
Personally go out and enjoy the world PVP while you can and then when the BG’s ship focus on what wins games.
If you’re a monster in PVP as enhance or something then play that.
If you’re a better healer than a DPS then do that.
Good day.
