Okay, looking through the feat lists I've come to a realization..
WoC is full of retards.
This thread is to pose mods/fixes to things like Feat Pre-Req's..
First on the list:
Expanded Spellbook. Pre-Req: Wis 13
I propose this Pre-Req be changed to Int. Why? Because it's a Wizard feat, and Int is a wizard's main stat.
Read over the feat.
I'd say no on this. It feels powerful (flexible) which means it's sensible for it having an expensive/odd requirement.
