It seems pretty cleat that at some point the Choose Deity option during character creation was available to more characters than Clerics (it should be available to everyone...) why do I say this? Well, my Multi-classed Paladin/Cleric of lathander gets dialogue options for (Paladin of Lathander)... so there's an entire choice of dialogue options written that don't get seen unless you multi-class (which wasn't going to be supported at one point, no?)
Can we fix this? Let people choose deities regardless of class please.
