If Zz'dtri believes, as Vaarsuvius used to, that arcane power is the only kind of power that matters, then a build designed to beat wizards makes sense. It's the flipside to Vaarsuivius' assumption that it's the wizard's job to fix everything; the idea that overcoming all the wizards is how you "win".

Being tailored to beat V might just be a side effect of being tailored to beat wizards in general.
