I got around 83 HK's earlier and 6 flag returns, was I farming? No. I play aggressively and I spend a lot of time in the graveyard and on the field. A lot of players play it safe and worry about their scores and they win BG's without many HK's. (psssst, secret, you have infinite lives in battlegrounds in world of warcraft)
The underlying point in this thread is the fact that we're part of a forum community where you can't share an experience or opinion without getting shot down by other users just for sport/attention.
@OP
Good job, I've been experimenting with Arms warrior to great success, I'm always in at least the top 5 in damage even when hunters are around and I just go for flag carriers/healers the entire time. It's nice because if EFC has 1-2 healers me and 3 people on offense can just go in and focus fire the EFC and take him down while ignoring the healers thanks to mortal strike.
We need more players like you experimenting with "unsafe" builds to push the limits of players in this bracket. While some players think Arms Warrior/Elemental Shaman/and Warlocks are weak on the field I've been seeing a lot more lately proving the classes strengths.
Good luck! Have fun!
