Hello and greetings from germany.
While I like Pathfinder and understand that combat is an essential part of D&D (bin there since AD&D), I REALLY don't like this ongoing trend that every class get's reduced to its combat value/abilities.
Take a look at the PF Universalist Wizard: 1st level ability "Flying Weapon"?! WTF?
That's one of the stupidest ideas I've ever seen. Really.
Or the Bard, who's pinacle ability is to *drum-roll*... RIGHT! Kill someone.
It's a bard for Tyr's sake! So let him be a bard swaying the masses not some doofus guy SINGING(!) in combat!
(That last part goes to all D&D)
Okay, after rampaging over PF, I'll get back to my point:
"Don't reduce all classes to their combat role!"
If you talk about balance, don't reduce it to combat balance. If you want to be great in combat play a fighter, if you want to be GREAT in manipulating people, play a bard!
A thief/rogue is a thief, not a battle-assassin (well, maybe not at first). The bard is a master of the word/story, not a battle-chanter, the cleric/priest should inflame the masses, not be a walking band-aid, the wizard should delve deep into the mysteries of the universe, not flung empowered fireballs around...
The exception to this are of course the warrior classes: namely fighter and barbarian. But in case of the fighter, they (D&D3) just messed up. Some additional feats and that's it?
(PF did some good here, but still not enough)
The fighter should be the one who REALLY controls the battlefield. Using tactics to spoil the attempts of their enemies, pinpointing weaknesses, holding ground against overwhelming numbers...
(Mechanic hints: changing his feats in combat, uncanny dodge, delaying action but acting before the triggering action, identifying monster types and vulnerabilities...)
So. Balance? Yes!
But please balance in an overall game sense, and not just combat balance.
