Aren't goblins supposed to say
 

"Ugly creature near my feet, me thinks you'll be good to eat" when they attack you?

I recall them saying that in classic.

I've seen plenty say that. Where aren't you seeing it?

Some had different lines -- Sol A had something like "...firepeak(?) goblins kill and maim" etc. I believe these texts do go off.

Are they suppose to have the same dialog as on live? In crush, orc say something like "man kills man, ape does not kill ape!"
Made me chuckle, but their not apes. I don't recall them saying that... though that was a long time ago, and it seems strange they would use a movie quote that doesn't fit their race.

They did say that on live, and although I don't recall the quote exactly, in planet of the apes it was more along the lines of just "Ape does not kill ape".

I think the "man kills man" was from the new movie. If in live, really weird they would have orcs say that. May as well say: Look up in the sky, It's a bird, it's a plane, it's D'vinn! :D

Yes.

There's a bug thread somewhere about this and other NPC taunts / aggro speak.
