Can a Cleric take both the Crusader
archtype and the Holy Warrior ACF? Holy Warrior says a character gives up both domain slots for full BAB + a d10 hit dice, while Crusader gives a cleric one less domain and fewer spells per day. In other words, they would be 'losing' three domains, even though they only ever had two. I'm not sure if it would be legal or not since the character isn't really trading domains in for something else, they just lose access to them.
