The abdurant champion Champion (complete Mage) is all about arcane boosted defence. The discription and flavour of the class suggests its primary ability effects mage armour, but mage armour is a conjuration spell.
"Abjurant Armor (Su): Any time you cast an abjuration
spell that grants you an armor bonus or shield bonus to AC, you can increase the value of the bonus by your abjurant
champion class level. Abjurant champions rely on mage armor,
shield, and similar spells instead of actual armor."
What seems right to you?
Is there (or should there be) a bonus to mage armour=class levels or not?
