Nostalrius Begins - Quality wow vanilla realm (1.12)

Are there any PvP benefits to going Goblin over Gnome as a Mage? I already have a Gnomish Engineer in my 60 Tankadin, but am just curious if having yet another way to blow Hordies up actually matters.

I'm not asking which one to spec. I'm gonna go Goblin simply because my Pqally could use a reliable source of Sapper Charges. I'm just asking how to best put it to use in PvP.

It's all personal preference, most of the time the useful items are the reflectors for the class you are playing against.

Although the boots are always fun.
