Note, the suggested build gets Cha to hit and damage as well, which of course solves the Dex issue. Overall, spells are still great and getting full spells and support on a slightly weaker combat chassis is generally better than just slightly stronger combat chassis but no spells. If you have any characters not using their Concentration in the party, the party is probably suboptimal. Similarly, any party that has any characters not casting 9th level spells is generally suboptimal. To this end, Valor Bard is one of the better ways to get a ranged damage dealer without compromising overall party power level.
Also, 16 casting stat isn't actually all that big of a problem even in Tier 4 (not that this particular build would have the issue). You generally begin to tend away from save-or-X effects anyways once LR becomes prolific.
