It seems odd the versatile wizard can't be persuaded to take GSF feats for the wizard bonus feats. What's the reason?
There are potential builds (i.e., melee vampires/wraiths) that exhaust all seven+ main feats and have no room for GSF feats, thus can't take higher tier AM/PM prestiges.
The current situation seems akin to fighters unable to take ITWF or GTWF for fighter feats. Are there balance concerns or carry-over rules from PnP?
