Probably not, but it's certainly a prince.
Trouble is, as we make monster classes, we want to emphasize a player's options in combat, rather than just pile on a mess of passive stuff. Too many passive abilities just puts the DM in the position of having to find more ways to challenge the group. Active abilities puts the onus on the PC to find solutions to encounters.
Edit: And it's worth saying, a creature who is limited to 'attack, full attack, maneuvers' gets boring pretty fast.
Remember that Gorgon requested in the OP that people not post a new monster until their previous one is vetted & added to the list. We don't want to saddle the guy with a backlog.
