I recently leveled an alt through a Timewalking campaign and then the Dragon Isles, and I was reminded of how unbearably annoying this snotty little toddler dragon is. I'm not sure who directed the voice actor they got for this role, but they should be fired. I found myself skipping cutscenes in Thaldraszus because I couldn't bear to hear it any longer. Your characters shouldn't be encouraging players to play the game with the sound off!
We've had some truly terrible voiceovers in the past (Sindragosa in ICC, Ultraxion in Dragon Soul... maybe Blizzard just doesn't know how to voice dragons?) but those were at least one-patch affairs. This horrible little shit is shoehorned in everywhere, and at this point somehow serves as a franchise mascot despite sounding like the redheaded one from Rugrats.
I'm incredibly optimistic about the World Soul saga and the future of WoW in general, and I'm hoping the great new direction the game is heading in can leave this one character punted to the back burner where it belongs.
