Spells: Shaman level 19 Spell : Affliction , Not doing correct damage at all really low!

[visage]

Currently the level 19 spell for shaman "Affliction" Is doing 30 dmg first hit , and only 6 damage a tick. I tested this on multiple mobs using a disease debuff etc. Still only 6 dmg . I remember this on live to be 30 damage a tick. Sources from Google , Alla etc mirror this too. Therefore I believe this spell is broken. Making it hard for level 19 shamans to solo efficiently. Thank you for your time.
