Nothing that one dispel can't handle. It your players have come to rely on these spells as a standard part of their characters, a dispel every now and then can really get'em to think outside of the box - or wind up inside one permanently.
on to the topic of discussion...
My gnome illusionist just made 8th level and I was considering taking polymorph self, but IMHO, its a pretty weak spell compared to other 4th level spells (Phantasmal Killer, Shadow Well, Shadow Conjuration, etc.).
Good points:

gives you the healing of a full day's rest (but only once)

possible flying, swimming, or waterbreathing abiltiy(within speed constraints of the spell)

Some forms may provide a slightly better attack bonus (like I WANT to be swinging at things when I could be casting spells).

+10 to disguise checks (Look I really am a badass - better take me out first!)
Limiting factors:

Mage armor, shield, and haste provide the spellcaster with plenty of AC (Don't need no stinking polymorph)

Most forms assummed will not have speech and/or access to equipment - No spell casting, scrolls, potions, wands, etc.

without (Su) or (Ex) abilities the forms (at least that a small-size caster can take) just seem pretty lame. Why would I want to be a completely neutered small-to-young-adult sized dragon without any equipment? So I can stand there with my meager pool of hp and get my little spellcasting ass kicked?

No gaseous form - gaseous form would actually be useful enough to justify choosing this spell as one of the two you get when leveling up.

No multi-attack. Who wants to be a Maralith with 3 broken arms?
I agree there was room for abuse with this spell, but in its current form its little more than a fancy disguise self spell - rarely worth a 4th level spell slot in my opinion. It has some roleplay usefulness, but ain't that great in combat situations.
