I hate that it is near to useless to play a character using a weapon other than their deities favorite weapon.
Dwarven Warpriest with an axe doesn't have a decent build with this restriction in play. Not many deities with an axe as a favored weapon, and even the few options out there greatly limit what the role playing would be like if you stick to the nature of the deity.
It seems to be unnecessary limiting, almost railroading...
