The popularity of the unique Night Elf culture Blizzard has created extends to Demon Hunters, a Hero class that is incredibly limited in Roleplay capacity, but extremely popular.
Tinker was a popular April Fools addition, but ultimately B-tier. As much as I want Tinkers to be playable, I doubt they would be popular if only limited to gnomes and goblins. Reason? There are many people who would not roll one if that were the only option.
Think of it this way. We know some people HATE Pandaren and would never roll one. If Monk class was limited to Pandaren because thats what makes sense, then the Monk population would be hella smaller than it is today. I don't mean Pandaren are unpopular btw. I mean the Monk class would suffer from exclusivity, if you regard the current Pandaren Monk population as the overall number.
Gnome and Goblins arent very popular, they are close to Pandaren in population. Tinker class can't carry a race people hate. The race choices need to be accessible.
I have nothing personal vs gnomes and goblins mind you, but my entire guild would never roll a gnome or gobbo fyi. They would be Engineer/tech theme fans who question Blizzard why they limited the choices to those races. And I would agree with that because honestly, why not.
