I believe I've mentioned WotC's hate of goblinoids before. Guess what? It still applies here.
Goblins have ability adjustments even worse than the half-orc's, are small (further restricting class options), and have barely any racial support (I counted one feat and one PrC). Their racial traits consist of the aforementioned ability adjustments, darkvision, and a +4 bonus to two middling skills.
That said, I don't really have any options but +0 LA. Goblins are bad, but not bad enough to warrant a -0.
