for soloing effectiveness, as the others have said, fire/dark all the way. i have both fire/dark and fire/kin at 50, and from my experience with both, /dark is the best at soloing effectively.

general stratagy is to darkest night a foe, kite it so it pulls 3-4(more if you're comfortable with it) groups of enemies around a corner and into a tar patch. fearsome stare -> rain of fire -> fireball -> firebreath look for the next pull. you'll be slaughtering everything.
