What's Interesting About This Dwarf?

There's something quite interesting about this dwarf.

It's something I'd sorta noticed on Leafy, but only in a subconscious way.

(Any ideas yet?)

I guess that people who have been levelling fast might have noticed it. But us slowboats with reasonable BC gear haven't.

(Clearer yet?)

I have to admit, when I had it pointed out to me, I was blown away - and I got very excited about the Lich King endgame.

And even more excited to get some alts levelled.

And if you still don't have a clue what I'm talking about, here's the full story.
