The only buff Vampires really need is the inevitable power reduction of Holy weapons, in my opinion. Outside of losing all their health to those, they excel so well at one on one combat from raw stat efficiency that their inability to be healed for much balances it out. Bringing a Vampire to a large 4 on 4 with healers doesn't pan out well, though.

This one is because receiving like 75% less healing is making a Vampire's lives pretty harsh in PvE. Prescribed Hi-Potions can't save you in Crazy Dungeons, Life Drain requires the enemy's HP percentage to be big and WIL from you, and Silvermists is not doing the cut while it drains too much Essence, and losing your status bonuses in the middle of a fight is pretty crucial, especially losing enough to end up being double-turned by monsters when you have average CEL.

It doesn't help in some circumstances, but the bright side is that food is 100% effective for Vampires.
