Start with demo then work ur way down in afflic.
the points in improved drain soul are important coz ull need 2 manage aggro with ur pet on elites.
Little tips on soloing elites:
first of all VW is much better tank then FG
FG is for killing mobs normally but when u go elite its only VW.
Buy the VW glyph (+20%hp).
your VW got an AOE aggro spell with 2 minutes CD, remove the auto cast on it.
Before u send your VW on elite use Demonic empowerment
and let him hit the elite when he is in range use the AOE thingie aswell (forgot the name, "suffering" maybe :p)
and always try to use the aoe aggro when Demonic Emp is up, that way he does lots more aggro.
Wait with Soulshatter untill the Elite is at 50%.
Dot and heal use shadow bolt when u get nightfall.
Thats it 4 now
Ah and when u see DK's on ur way do /spit on them. (Doesnt matter allies or horde)
