Heroes of Might & Magic III: Horn of the Abyss

The race of dwarves? No need. Many people might want an elf race, or a vampire race...

You're wrong here. Don't confuse the races of dwarves/humans/elves with vampires. Are vampires a race? I think it's silly – they're just a type of undead, unlike the three mentioned above.
And dwarves don't necessarily have to be called just dwarves; you could come up with some other name.
P.S.: Maggot, do you have anything against a pure human race? But it exists. And that's fine.
P.P.S.: In general, Stick is right; some kind of rogue class would look good there...
