I pvped on the weekends (holidays) and had a blast at doing it.
I went as my main spec, Prot.
My goals: Run flags in WSG, Stay and Defend BS in AB (the shout out incs), Tank and spank in AV, Run around Eye of the Storm and do what was needed the most (cap and D towers, or run flags), I hated Strands..so I actually would skip strand's weekends, would Tank boss in Isle of conquest.
Having a good healer and a DPS or 2 with me made all this easy and awesomely fun.
If Prot isn't for you, I would say a Arms spec would then be better as that is what others seemed to be.
