I have a swordsage/paladin/swashbuckler (though I don't think the class is itself relevant), now with Intuitive Attack. When I am unarmed, I get an Attack Increased buff: from Intuitive Attack, right? But when I equip a weapon suited to Intuitive Attack, such as a mace or sickle, I get an Attack Decreased debuff as well as the Attack Increased buff. I started and leveled a new character to test and this debuff business only shows up for the mace-equipped toon when I gain the Intuitive Attack feat. I believe the attack figures add up correctly in each case I have seen, but I wonder why there is a buff and a debuff involved. Since the math works I can live with the debuff icon, but I am curious.
Also, I did search and something similar is reported here:
