"Very strongly implies" is not what is demanded of Fighters though. Fighters have to have ironclad, unequivocal proof.That you have to train to level up in 1e fairly strongly implies the existence of places where such can be done - martial arts or mercenary training schools, thieves' guilds, mages' guilds or labs, temples, etc.
It's explicitly called out for the Monk - they have monasteries where they get their training - and Bard, for what that's worth.
The same standard should apply to everyone. Either the Fighter having wuxia powers means that wuxia powers have implied justification--just as Wizards copying scrolls "very strongly implies" their connection to an academic and/or hermetic tradition, or Clerics having this-that-etc. "very strongly implies" the existence of monasteries that train them--or Fighters having wuxia powers needs firm, irrefutable explanation and so do Wizards and Clerics etc. etc.
Otherwise, it's a blatant double standard, predicated solely on "Fighters aren't part of the caster club, so they get shafted."
