Huh.
Just realized that there *are* a number of feats that directly translate into class features, arn't there?
Toughness for example bumps you up one HP category. Armor training does the same for armor and weapon training for weapons. They'll probably also have the bonus to reflex/will/fort feats. Seems like because these feats exist, they have to balance class features in such a way so that you don't just take the class that gives you the most "virtual feats" first (fighter for example) and then multiclass into another one via feats.
It looks like the fighter has somewhere around 7 or so virtual feats up on the wizard, so that's a bit odd. What's the wizard getting in return? Cantrips, the spellbook, implement mastery? What else? Ritual casting? Skills?
