Man-thing said:When I look at monster classes it seems to me that all monsters are born at 1 HD but become valuable as monsters at a later HD and the MM shows a typical adult.
Monster classes aren't core.
In Core rules, there's no such thing as an ECL 1 gnoll. A gnoll is not a possible character until ECL 3 - 2HD, +1 LA.
In Core rules, there's no such thing as an ECL 1 porpoise.
Therefore in Core rules, there's nothing wrong with the porpoise - which has a BAB of +1 and one feat due to its two animal HD - having the Weapon Finesse feat.
If you introduced a porpoise monster class, that got one hit die and one feat at first level, and the second hit die at second level, that porpoise would not be eligible for Weapon Finesse. But the standard MM porpoise is.
The porpoise gains one feat because it has two animal hit dice... not one feat because it once upon a time had one animal hit die, and now it has two.
