Man, I just love this kind of Rhetoric! Such insightful and intellectually stimulating debates these are!

Dude, if you're going to make a wild, unsupported claim loaded with hyperbole, at least have the common decency to get basic facts straight. Dire Bear is 12 HD, a level 8 Druid couldn't turn into one.
And go ahead and turn into a dire bear and lose all your gear for a nice str check, size large (if only there were level 1 potions that let my fighter do THAT!), and some natural armor (to go along with your pathetic touch AC). My Fighter will do just fine with his gear, feats, and full BAB. Not as fine as he'd do if he were a Warblade or whatever, but fine enough...
Yeah, I forgot about the HD thing. So, Polar Bear – kosher, right ? I’ve got my Polar Bear with his speed, improved grab and 3 attacks, you have your Fighter 8 with his 2 attacks and feats.
And to be honest – you will outdamage me. Not by an overwhelming deal, but you will be ahead of me in damage.
But that’s not the point. The point is that a druid can compete with you, and he happens to be full caster with 4th lvl spells at that point, apart from his melee capability he can bring stuff like scry, fom and reincarnate to the table. And the fighter, apart from his damage dealing can bring … ?
Of course, all this is irrelevant because a 3.5 core Cleric walks by, casts the holy trifecta and looks at both of us with a confused stare and asks “what are you two arguing about ?” at which point the Fighter can go back home and the Druid can start quickly looking for things which he can do and the Cleric can’t.
Pathfinder fixed it by making sure that while Fighter remains one-dimensional, he at least is a king of the hill in that one dimension. Nobody gets close to his damage-dealing capability. The days of full casters replacing full BAB classes in their intended role are gone.
