hey guys what do you guys think is a better spec used in pvp. Both are lock/chloro however im honestly not sure if am is worth it or not, if its debatable is this a viable spec

combo of defile/soul purge can provide burst along with a pet for extra dps and still have all the heals out of chloro. however necro gives extra heals and buffs too.

or is the standard chlorolock a better spec with am's +15% dmg
