The strange thing is that the CB -- and perhaps therefore WotC as a whole -- are also playing "word games" regarding Staff (weapon category) and Staff (implement category). They seem to regard them as the same thing.You're playing games with a word that has 2 uses. Mace as a weapon group/category and Mace as a named weapon. I really which they had avoided that nonsense. What is an "attack"?
A staff (implement) is both an implement AND a weapon as quoted directly from the PHB errata by me. It specifically is treated as a quarterstaff which is a member of the "Staff" weapon group. Staff Fighting allows you to treat a Staff (weapon group) as a double weapon so you treat it as if you're wielding it in each hand. Please stop playing word games.
Try equipping a magical Quarterstaff for a vanilla Sorcerer -- one with no special feats. He'll get the full enhancement bonus to attack and damage.
I find it hard to believe they'd make such an obvious mistake if it were a mistake.
