Continuing the hating on Pathfinder, I'm really unhappy with the PF barbarian.
The problem with it is that you gain a lot of fairly useless abilities over time, and never really have enough rage points to use your useful ones on a regular basis. If you want to spam the really powerful stuff, you end up being a five-round-wonder. It's just not all that great, but as was said earlier - PF doesn't really "fix" the melee-magic imbalance at high levels. In my opinion, only tome of battle does this, but it does it by making melee a lot more powerful and giving melee something fun to do with standard actions without having to finagle themselves into a pounce ubercharge situation. But since it raises the overall power level of the campaign, many DMs disapprove.
I'm playing a melee character in a homebrew campaign that uses the pathfinder barbarian rules. What I've found it's good for is 2 levels of barbarian. That gets you enough rage points that you can spread them out over the whole day and rage a fair amount, without using the powers. The one power you get is the one that gives you a temporary speed bonus, because that's relatively cheap and when it comes in handy, it comes in REALLY handy. This way, I can rage for most of the important fights each day, and I don't "waste" my one rage for the day if I blow it the round before the wizard does something clever to incapacitate the crowd of enemies I was about to beat down.
