I am planning a take on the 3.5 "Friendly Berserker" build for PF solo play. The old way to do this was to build a Bbn//Clr, taking levels in FrB when you qualify, and at some point taking levels in the Champion of Gwynharwyf PrC from BoED.
While my GM doesn't object to 3.5 material in PF, he DOES (and rightfully so) object to the 3.5 PrC Frenzied Berserker.
Just recently, I've found Kain Darkwind's FrB (http://paizo.com/paizo/messageboards/paizoPublishing/pathfinder/pathfinder RPG/conversions/frenziedBerserkerAsBarbArchetype) archetype, which fixes (along with PF rules) the insanely OP Power Attack potential presented by the old PrC.
Fortunately, I can use some stuff from UA, most significantly, Gestalt rules, Flaws (with some barbarian flaws from a 3.5 issue of Dragon) and the "Paladin of Freedom" variant (adapted to the PF paladin).
This, combined with the fact that my GM is allowing the Cavalier of the Order of the Griffon, from 'Cavalier Orders', and that the Mounted Fury Bbn archetype, from APG, doesn't have any class features that overlap with Kain's FrB archetype, creates some fairly nasty potential for a mounted rager.
I have two questions.
1. If one side of the gestalt combo was always FrB (mounted fury), in what order would you combine the following classes on the other side: Fighter (for combat feats), Paladin of Freedom (for survival in solo play), and Cavalier of the Order of the Griffon (for mount and more 'freedom fighter' flavor)?
2. Has anyone else tried a "Friendly Berserker" in PF?
Chances are I will figure it out, but I was just curious if others had ideas or prior experience.
