Shizune - She is currently outclassed by healers such as the Water MC and Karin.

Shikamaru - He is very, very useful in certain teams like with the Fire MC for a straight-out control team.

Ino - It seems she is only useful when pitted with Shikamaru and is weak compared to the other healers.

Choji - Chozu just dominates his son in every way.

Shino - Kisame outclasses Shino unfortunately. However, GNW Shino is a great replacement.

Some of my 2 cents.
