Intent/Spirit of 3.5?

[Pharaoh's Fist]

I imagine that alot of the complaints which players have about Paizo's 3.75 are extremely similiar to complaints made when WotC bought TSR and revamped AD&D into 3rd edition. An alteration of some basics while still keeping the general shape the same that actually turned out to be an improvement.

Are Fighters still screwed by a Solid Fog or Grease spell as much as they were under 3.5 edition rules?

If yes, then back to the drawing board!
