Question for those converting from 3E to Pathfinder?

Pathfinder has most of the same stuff as 3.5 does, but it also adds additional options and corrects a few infamous flaws.

 For instance, all core races now have two +2 and one -2 to their ability scores, except humans and half-elves, who get one +2 to an ability score of their choice.

The Pathfinder (Alpha 3) rogue has all the same abilities as the 3.5 rogue — plus an additional set of rogue talents which are gained at every even level.  (The 3.5 advanced talents can be chosen as rogue talents starting at 10th level.)  These talents include the ability to disarm traps in half the normal time, the ability to hide and move silently at full normal speed without penalty, or Weapon Finesse.  (Incidentally, Hide and Move Silently are consolidated into one Stealth skill.)

Another main issue they're working on now is the polymorph problem.  Under 3.5, an 8th-level wizard could turn into a digester with a 20-foot, 4d8 damage cone of acid, or a dire lion with Strength 25.  In Pathfinder, they're dividing the spell into a selection of spells for each creature type, with higher-level spells allowing larger and more powerful forms.  Each spell specifically lists the special abilities it grants, as well as a fixed bonus to physical stats.

One of my favorite changes is skill ranks.  Instead of getting 4 x skill points at 1st level, you get the same number of points at each level.  If you have any ranks in a class skill, you get a +3 bonus to that skill, which makes up for the loss of the multiplier.  If it's a cross-class skill, you just don't get the bonus.  That's it.  No half-ranks, no keeping track of which points go with which classes for multiclass characters.  Best of all, you get the bonus if the skill is a class skill for any of your classes.  If you've ever tried to build a high-level multiclass character in 3.5, you'll never want to go back!
