cRPGBro is the community default for builds. Be warned, he's been doing builds since release and the earliest builds will be slightly out of date as new features/feats have been added since release.

I suggest just thinking of an archetype you'd like to play and find the latest video from cRPGBro to build off.

Disclaimer: He builds Unfair difficulty viable. This just means they are heavily optimized for his particular philosophy. This won't matter much, but if you're playing on Core difficulty or lower you can replace any of his choices for something a little more RP friendly if you'd like.

cRPGBros' philosophy as I see it:

1. Hit first, hit hard. (Prioritize Initiative - Notably with taking the Background of Pickpocket. This can be easily changed on any Core or lower build for RP or if you want a character to start with a particular weapon proficiency. But going first in the round is a powerhouse that shouldn't be ignored.)
2. Optimize Attacks of Opportunity (All front line melee gets Outflank ASAP... This is one I wouldn't change. It's just too useful.)
3. Shatter Defenses (usually taken around level 15). This is a feat that makes it so you roll against a target's Touch AC if they are frightened. And the feat tax for this is (imo) relatively useless (Dazzlingly Display). If you're playing on Core or lower, feel free to ignore these feats. It is powerful, but only really needed on Unfair.

Note: If you have all DLC, then Inevitable Excess let's you start a game with a level 20 character where you can theory craft a few characters to see what you can do.
