I'm sorry if this is covered somewhere else, i looked, and could not find.
I understand that bloodline powers and bloodline feats are directly tied to sorcerer class level, but are bloodline spells tied to the class alone?
this would make prestage classes even weaker. because sorcerers are already limited in spells known, but to be giving up one spell known per level is harsh, and not really worth it.
Example: a 6th level Sorcerer, 10th level loremaster (yes it is odd but possible) would have the bloodline spells of a 6th level sorcerer (3 bonus spells vs 8 bonus spells)
the other problem this causes it that then all specialist abilities from wizards should be tied to the class, not wizard caster level. if not then wizard is even more powerful then i thought.
Example: a 5 level wizard, 10th level loremaster specalized in Divination would have the specalist abilities of a 5th level wizard, including bonus spells per day.
hell, the way it's set up, what would balance that out.
