I will be using the gear primarily for random bg pugging and i'm looking for a balanced set.
Argas x2 vs Argas + Advisor's Ring.
Uninsured bracers vs Cuffs of Black Elements.
I would almost hate to say it but I barely ever see Rdruids go Oom, I personally would say try going for more Int over Spirit. I dont play the class but from my experience trying to target healers in the BGs, they generally last the longest when it comes to the mana pool.
Personally i've gone oom 3 times out of the like 8 bgs or something i've done.
Those times i've been constantly mid fighting though, not escorting fc or something like that.
And ye havn't considered going with Brilliant Spellthread, i guess i'll have to purchase another leg piece
