Never put a single point in intimidation myself, and never needed more than 105 effecting mercantile. After finishing a game in wich i invested in stealth i never played without it afterwards, you can just skip many parts without a fight, and in DC that was much appreciated. I'd like to see gun nut instead of one of those filler feats, and 1 point in int would decrease the number of needed point in those crafting skills.
