We've very closely covered the lack of Gnomes in any of Blizzard's major cinematic pieces so far. We had hoped to see them in the Wrath cinematic, but of course Blizzard went a completely new direction with that one (retelling the story of Arthas rather than showing players fighting), and so they weren't there either. In fact, the problem has gotten so bad that at least one person has remade the Burning Crusade cinematic, filling it with Gnomes just to see what it would be like. And while we've gotten some snide comments from the Blues before ("they're there, they're just too short to fit in frame"), Bornakk has finally given us an honest answer as to why the Gnomes haven't been show in cinematic form: they're just not awesome enough?
Wait, that's not what he really said? Well that's what we heard -- he says that the cinematic folks go for what seems most awesome, and Gnomes have just never been a part of that combination. He says Trolls have gotten nearly the same treatment, and while that's true, you can see a Troll for a split second in the Burning Crusade cinematic -- they haven't had the complete shutout that the shorter denizens of Azeroth have had so far.
In fact, Murlocs have gotten more screen time than Gnomes have. But the good news is that the more Blizzard leaves Gnomes out, the more awesome it'll be when they finally appear. The cinematic team can't leave them out of the game forever, right?
