So far, the Gobbs have been the most varied thing I've encountered and I think they're fine enough.
Kill em one moment, talk to em the next. They look scrappy while still feeling less threatening on their own.
I'll say it now, I wouldn't mind a goblin companion after seeing Larian's take on them.

I think that disconnect between the graphic styling is intentional - some of these creatures aren't supposed to be natural afterall.
