To that degree, i completely agree.
BUT
If everyone in the party optimized something of that caliber, then the truenamer goes back down. the only reason its so good in comparison is because the party lacks the skills to make characters as good. (i generally lack to patience to make such a complete character, not to mention to motivation considering the character would never get played)
ALSO
On second inspection this guy has a glaring weakness in his touch AC, my thrower (Lil' Tosser) can probably take him out in a single round…
Though i would be a little worried about a few of those utterances.
Out of the party, i think the person that would have the most impact on that truenamer would be… either Dans Barbarian(with some minor tweaks) or maybe Pauls Wizard(depending on spell list) (in no particular order)
Sorry Brigga, but i have little faith in fighters… prove me wrong ;)
