Just to clarify: Dhampir are not expressly meant to be a melee/ranged race to the exclusion of anything else.
They are meant to be a race that has some synergy with melee and ranged builds, while also having other synergies with other kinds of builds.
Thats what I meant by specific synergy, you cannot have a race be amazing for all builds, some will always lean towards a particular style but offer things for everyone because ultimately for a lot of people (myself included) we pick race based on what we like, rather than what is "best". In the same way that gnome offers some smaller bonus if you used their weapons, its clearly designed more for an int user. It would be weird for me to demand gnome also be great for my specific paladin build just because I, personally, like gnomes. You should definitely aim to give Dhampir more towards non str melee than it currently does, but not at the expense of it feeling like half of the stuff is useless. For starters, some healing SLA of some kind would go a long way because then it would be a reasonable option for any class with limited self healing. You'd be tied to negative, sure, but at least you wouldnt really on the 5 people in the game that play negative alchemist or dark apostate to heal you
