The Crusader class write-up and specializations feature language that is either an exact quote or paraphrase of many of the QQ comments in the Kickstarter about the lack of a warrior class. There were people bitching about how they didn't want to follow a god. What do we get? "Proficient in most melee weapons and can cast beneficial spells when following a god."
Which directly counteracts the class write up (that was obviously written before the specializations.)
"The Crusader is a powerful knight whose devotion to king or deity is so great that he has been blessed with divine powers. A paragon of virtue, the Crusader commands the battlefield and defends the weak. Brave and bold, the Crusader is always at the front of any fray, guarding his allies against harm with armor and faith."
The timing of the "you can be a warrior too" information coming right on the heels of all the QQ, the fact that the original "lore" update only makes mention of Crusaders as a holy, paladin-archetype, and the previous execution they've had all point to one thing:
Making it up as they go.
