It's an orc. It's good at hitting stuff and bad at abstract math. Yes, it is arguably the best melee race in core, but it's not in need of a positive level adjustment. +0.
Still an orc, but with less strength and better ACFs. Probably weaker than its full-blooded parents (on either side), but there's definitely still a variety of reasons to play one. +0 LA.
Next are otyughs!
