Itemization heavily favors STR based toons. DEX toons need DEX and STR and INT to be self sufficient.
Why does any character need to be self sufficient? Wouldn't making 4 characters be good at what they do and compliment each other make more sense? Not that my Dex characters don't dabble in witchcraft and stuff but they generally stay away from things that require tons of Int to work.
Is there any reason to put Str or Int on a Dex character other than to allow Str or Int abilities/spells to be effective?
