The expert w/this feat vs warrior w/weapons discussion doesn't seem terribly relevant to me.
What is more interesting is this claim Oslecamo made in his first post:
There's also no quest for taking care of that wandering angry giant. His natural and manufactured armor was no match for the villager's boos and hisses.
How many Experts with this feat would you need to take down, say, an Ogre, reasonably consistently?
Ogres aren't smart enough to decide to use hit and run tactics on a bunch of villagers so this one is going to use its greatclub in melee range, meaning it'll face the full brunt of the villagers' discouraging.
On the other hand, the club does 2d8+7 with a +8 attack bonus so, even if they're turtling with the encouragement function, one expert is going to die most rounds. Let's not worry about whether the average villager would be willing to face those kind of odds and just see how effective they are assuming they do fight.
The ogre has 29 HP so 8 Experts can beat it if they win initiative, 9 can beat it if they lose.
How many Experts are there in the average village?
Also, what is the CR of a human with 1 level of Expert? An elf warrior 1 is 1/2 CR. If that carries over then these Experts are actually higher CR than the monster they're fighting (Ogre is CR 3.) CR isn't much of a measuring stick but still...
