I have a 5 box of Pally and 4 Shammy

I see a few posts that Shammy are now getting destroyed in BG and have lost a lot of the burst that we once had. Has anyone given any thought to a different 5 box team setup? I enjoy a mix of both PVP and PVE.

I loved my pally and shammy team but I am also keen for new experiences. What else works well for both 5m instances and for pvp ?

Thanks,
