I am curantly gearing up my shammys and i'm doing a mix of both atm. I do SP HC each day as i up till today wanted/needed that shoulders from the last boss. which i got the last of 4 out of today, grats to me And then i make sure to atleast do the PVP daily and i normaly do some more as BGing/pvping for me is what i enjoy in wow mainly. And i have lots of fun BBQ'n hords in BGs

But a good tip for AV that id like to share is:

When i enter and is w8ing for the gates to open i normlay will have the lead so ppl will notice me and i say in /BG something like this: "i'm a 4elly shammy boxerer and i need 1 healer and a few other dps to join me defending DUN(allie)" and ppl normaly go "count me in".... they all get this really friendly like we will win with this guy on our team additude. And i take them down to the brige before DUN, stand on a spot where the towers will suport... Add a healer to your grp and tell him to keep you alive and you will kill anything.. tell the other dpsers to kill melees that attack you... That way i normaly will hold the bride unpasabol for the hords and the normlay pve allies will do as allways, galv, towers, drek and we win with the hords standing and pushing on me the whole game.

Try that and i think that you will enjoy it alot more then the run down to drek and make sure you have all the tons with you etc..
