I disagree... Items like the Blue Suede Shoes, and the Garbs of the Made man, or the Royal Ball Gown, give CHA bonuses. I also believe there is a circlet or something that gives a CHA bonus. Do we really need MORE CHA being thrown around? We already have enough of Layonara's poor single men killing themselves over the likes of Daniella, Jaelle, even Alantha (yes, even her). And we have enough broken hearts due to people like Flynn, Connor, and even Abiorn.
Also, compared to Stats like Str, Con, and Dex, extra CHA for the CHA-based magic users has more benefits then an increase to any other the others. Str increases Carrying Capacity and adds +1 to Melee Damage per 2 points of Str over 10. Con adds 1 hp per level per 2 Con over 10, and add one to Fortitude saves. Dex adds 1 to AC (which can be capped for those of us in armor) and adds 1 to reflex save per 2 points over 10. Cha increases the number of times you can cast, and increases the DC of spells... Like Weird... Thunderclap...
In Short... I don't agree...
