Should goblins be aggressive?

[Valmonte]

Lore wise goblins are mostly friendly, as well as Sylphs and Quifims or whatever are those things that work on the limsa lominsa ships, which is why there are almost no aggro enemies from these races. Makes a lot of sense.

In other words:

No.

Sylphs are mixed bunch when it comes to what little lore that's available for them, but they can be hostile just ask the Garleans.
