Absolutely awesome archetypes -- would even like to see more on the official release, but...fighters are frankly quite bleh. You are given lots of cool choices and powers for the other classes (although the rogue could use a little more work), but if I choose champion I get a 5% crit chance increase? Even the base rules gave other bonuses for champions at higher levels. And why not give some of the choices more proficiencies? Arcana for a spellsword would make sense. Frankly, with a 4 party limitation carrying a fighter becomes a liability -- paladins make better tanks, rogues do more damage, and rangers are better archers and dual wielders. What can fighters do? Well they can fight, but without any special buffs or abilities that their counterparts have, they become a decidedly poor choice.
