I was going to try boomkin because I have never really played a ranged dps.. but not sure I want 2 dps specs
thought guardian would be good, but my secondary stats are the exact opposite so I feel like my tank spec will always be sub par
resto I feel would be fairly decent reusing the gear I have. I have a lot of crit and multistrike... not a lot of haste though so not sure how well that will work either

I feel like I am still going to need 2 full sets of gear + more if I get into pvp again

I vote resto cause OP

boomkin!!!!!
