Looking at barbs they are kind of focused too much in one area to the point it's a little silly what I'm talking about is terrifying rage, 28 barbarian fear Aura is -7 ab does no one see this as a bit absurd? Some AoE thing that is up the entire fight that cancels out a divine favor + bless and aid. When you think about it, it actually doesn't help barbs themselves that much but makes annoying dex builds with already high ac that much harder to kill.
I suggest something like capping the fear reductions to 2, and buffing mighty rage to give 5(or maybe some scalling number based on barb level) DR vs all non rare damage.
