One of my players can't play anymore and a new guy is about to join.
He said that he is thinking about efreeti og djinni bloodline.
What would you tell him here? I mean .. the efreeti is good because of the fire resistance.. but all his bonus spells are useless later due to the enemies resistances.
I'd tell the player what you just posted. He'll have resistance to fire, which is helpful, but many of the enemies in this AP will also have resistance or immunity to fire damage which will effectively neuter the character in many encounters.
