Soul Driver before and after Chaos.

My opinion, it still is, but will get replaced easily with the new skills.

Vampire, Is now a viable healing skill with its upgraded mob count.

Sharkwave, is still good, considering it's long range.

Flame Gear with the new DoT formula, it's an effective way to train.

And Piercing, high damage, but slow animation.

Except Vampire still sucks. If you're a NL, you heal more from drain. If you're a Shadower, Chakra does a better job of healing. So pretty much, the only class that'll get much out of Vampire is the DB, but that said, Vampire is hardly reliable healing at all as it only recovers 5% of the damage per hit at max level.
