1 Level of Cleric with Pride and Luck means you are pretty safe. Re-roll any 1's from Pride, and Re-reroll and die from Luck. You've got to roll 3 1's in a row to attack your party. Then you still get a chance next round where you again get at least two rolls for your Will (assuming you've set yourself up where only a 1 on a Will save fails.) That's not too hideous.
Fact is, that unless you have insanely good saves (from levels and/or loot) and have done some sort of dipping into a cleric with the appropriate domains, you will screw over your partymembers regularly. A PrC that only works in a party situation under such extreme circumstances, definitely qualifies as broken in my book.
Example. Bar6/cle1 is needed to qualify for FB, assuming you want the domains to help control the frenzy. Now, I dont have my books at hand, but going from memory, that should give him a +4 base will bonus. He wont have any spare feats to spend on Iron Will or similar feats, so they will, if wanted, have to come later.
So at 8th level, when he gets his frenzy ability (bar6/cle1/fb1) he has +4 base will save, and must roll vs DC20. Even with a generous DM, that doesnt seem like good odds.
Of course, you could make a bar2/f4/cle1/fb1 type, giving you 3 feats more, which could bump your Will save some. But unless you have a monty haul DM, you will still be far away from being able to control the frenzy.
Sure, spells like calm emotions can help, if your team has access to them, but lets face it. A FB is a ticking time bomb that any sane DM should ban or at least change.
