In the spirit of today's final question, I'm gonna blame Ghostcrawler for something completely unrelated to his job. Greg, buddy, I need to get paid more than once a month. Ikea doesn't shop itself.
Side note: Alex, what were you on when you made this image?
If the language (Troll) was changed to (Zandali) why wouldn't they change the language (Gutterspeak) to (Forsaken)? And for that matter, what reason could their have been to not let Worgen speak (Gilnean)?
Well, there's no real reason to change Gutterspeak to Forsaken. Gutterspeak is the name of the language (which, by the way, only exists for gameplay reasons). The Troll language is called Zandali, so changing it from "Troll" to "Zandali" made sense, at least. And Worgen would not speak Gilnean, because Gilneans speak Common, like pretty much all Humans.
