I assume that you're an elf player, so I can understand why the comic relief and levity may be off-putting. I on the other hand personally love how comedic and crazy Goblins are. I really find other races kind of stuffy and boring, while Goblins just seem like they're always having a great time. Like other races would preserve a forest, make sure the animals/environment is protected, and try to live in harmony with everything around them. Meanwhile, Goblins will clear cut the forest, murder every creature they find to make a buck, put up a luxury casino in the wasteland they just created, and then "accidentally" set fire to the casino destroying everything they just built.
I just think that's great.
