Considering bards have lower damage compared to other dps classes, and rely heavily on crits to deal burst. Also my bards dex is about 500, with hawk eye i gets about 585 dex, which then translates to 585 attack power. its not that OP, yes with 1k dex you would get about 150 dex. But really at the higher levels the small boost is only every going to be 15% extra dmg.
