Berserking has a 0 Gear Score?

[Illidaos]

I am new to the forums, and I apologize if this was covered in a past post.

I have Quel'Delar, Might of the Faithful, and I am a DPS DK. I recently replaced Rune of the Fallen Crusader with Berserking for obvious DPS reasons. However, Berserking is listed as having 0 GS and Fallen Crusader has 15. I am confused about why that is, and any information would be greatly appreciated.
