4e lycanthropes have me confused

i have always known all lycanthropes to have 3 forms:

(i) humanoid (as in, resembling a standard humanoid race);
(ii) animal; and
(iii) hybrid (typically a humanoid body with animal head and/or other parts).

however, in 4e:

(a) every lycanthrope has a change shape ability that references only two forms: humanoid and animal--no mention of a hybrid form;
(b) every image of a lycanthrope is in hybrid form; and
(c) most of their attacks can be used in only humanoid or animal form--no mention of which can be used in hybrid form, if any.

now, i can draw my own conclusion of how this all works together, but it just seems poorly presented to me. every other shapechanger in 4e (except the jackalwere, which suffers the same issues as the lycanthropes) makes reference to every form of the creature in its stat block (e.g., lolth, yochlol, lamia, hag, etc.).

perhaps, this needs correcting.

nagpa

one addition to nagpa fluff: after being transformed by the primordials, the nagpa fled to and continue to reside in the shadowfell.

shambling mounds are fey

yet another, with more to come.
