Even though I've been collecting since forever, still don't have enough of these commonly needed items.
No to unicorns, dragons, manticores, chimeras, and other 'prestige' critters that are rarely encountered but have been produced in plastic many times.
Dissenting voice. I for one am a fan of "prestige" monsters - Unicorns (only 2 or 3 different ones in PPM and this one is the best I've seen yet), Dragons (As long as they are different than those we currently have), Manticores (only a couple have been produced in PPM and most aren't very good), Chimerae (As long as they are different), Hydrae, Gryphons, Hippogryffs, etc. Whether they get used often or not, these are "Tent pole" pieces which bring in new collectors and keep PPM lines viable.
I've been collecting PPM since the Alpha release of MageKnight and have watched quality improve by leaps and bounds. However, the only thing that keeps these sets viable is the continual infusion of new blood into the consumer base as older collectors drop off either because they "have more mini's than they can use / have room for," or just don't have the money for them, or they decide to try their hand at painting their own, and new collectors frequently want these prestige monsters, as well as common beasties like orcs, goblins, ghouls, zombies, and various other tribal types that people have complained "We Have enough of these already." Mr. Mona has to walk a delicate tightrope with the set list from each set to make sure he includes enough "prestige monsters," dungeon dressing, unique critters that he wants, PC types, and grunts to keep the vast majority of players happy and he still gets complaints about one or two pieces in every set.
