I think if a rules set wants to have elements that are significantly inferior to other elements on purpose, it would do well to call that fact out so that people who are just playing what they want don't accidentally fall into a trap while those who are more mechanically minded neatly avoid such pitfalls and still produce the character they want to play.
Unfortunately that requires game designers who are able to recognise when they have created a mechanically inferior option so they can label it as such.
I guess I just DM/play/read differently.
To me, the flavour of these races (particularly that of the Shade*) already implies that they will have strong weaknesses, and any players paying attention to the text will realize that and either accept it or pass on the race.
Any players not paying attention to the text... well, odds are these races will be kindof difficult to incorporate into your campaign anyway, if you don't spell them out as options from the start.
To each his own, anyhow. I'm sorry the design is frustrating to you, and hope it doesn't negatively impact your game experience.
(For the record though, and I don't
think this is imparting a bias on my opinion here, I don't actually view the Vryloka as that mechanically bad. Perhaps more complicated to play, in the way that an assassin is more complicated to play, but that's why it's in a supplement rather than the PHB or essentials book.)
*The Vryloka flavour presented in the excerpt is a little confusing in places.
"She offered to them a powerful blood-bonding ritual that would grant them the
vitality of vampires without subjecting them to the taint of undeath. These human nobles became the first living vampires—blessed with great power gained at the
price of their own vitality."
Seems like a pretty bad deal to me. =P (And the fact that "Living Dead" explicitly spells out that they are in fact "tainted by undeath" is another kick in the pants.)
