Also, never target barbs if you are a sin. Just a waste of time.
That's not entirely true, some sins are actually very good though it certainly is a challenge. However if they come up against a skilful barb they need to play dirty:
Purge > Pot > 3 Spark > Stealth when it goes wrong etc
If you come up against a barb who is poorly eqquiped then it's not so bad. Equally, if you come up against BigBaetFarid who is geared to the max but cant fight to save his life then you are fine
