Shadow leecher ... Hmmm

After getting level 70, i was invited in one of the instance where we killed a Murmur boss. Interesting and surprize to me was that people invited me as DPS and not as a healer. Me, Druid(tank), Paladin(healer), Rouge and Mage did the whole run without a single wipe and quite fast. it showes that blizzard gave a priest one more role apart from healer.
Here is my leech build if we ever need one.

in Build u can see i put points into Silent Resolve and Shadow affinity to lower aggro while casting spells.
