In your opinion, does it make sense to structure those martial builds around the assumption that the party Wizard can provide those characters with consistent castings and re-castings (even using Imbue With Spell Ability & Karma Bead cheese to augment spellcasting level) of the Polymorph Any Object spell?
This way, the Tank, Rogue, and Archer can all amp their Int/Wis/Cha stats while being assured that their physical stats are cranked through the roof via consistent and spellcasting-level-boosted (to counter Dispel Magic strategies by the DM) PAO conversions into creatures such as Kelvezus, Firbolges, War Trolls (MM3 book), etc.
-------------
This way, the pre-generated stats of these high level martial characters do not have to waste their level-up stat boosts to traditional stats like Str/Dex/Con.
Wizards can do a whole plethora of tricks to crank their spellcasting level from 1 to 10 (or so) levels higher than their actual level, beyond the obvious Spell Power boosting via PrC's like Arch Mage and Spellguard of Silverymoon.
The beauty of all this is that the martial characters can now have crazy-high Wis, Int, & Cha stats, while dumping their physical stats. Meaning they can have great skill ranks, a nice Will save, and pretty faces.
This, of course, assumes DM complicity in such a collaborative party structuring strategy.
