Understanding Zombie Race-Class

"Zombie is sometimes a race, sometimes a class. It depends what other creature types are on the card."I am actually glad this was brought up, as it is my biggest pet peeve about creature-typing. Why are humans the only race that can't synergize with their undead counterparts? It doesn't mechanically or flavorfully make sense that Discordant Piper, Dread Wanderer, or Festering Goblin would owe any allegiance to their respective races; isn't the point of a zombie that it loses what it once was?And if mechanics are the sole reason, then again, why are Humans the only race omitted? Human tribal is really only a problem in Modern and Legacy, so bannings can easily be made if there would truly be an issue.Just not sure what the justification is for this dissonant articulation of Zombies.

Humans are already so over-represented, we thought it was a spot we could let other creature types shine.
