I think that endgame craft and combat are similair.
Combatant clears next content - for what? To get new drops and to be able to gearup to clear next content. I don't see any great formal difference with crafters. Able to craft artisan & masterbook tokens = t5, Supras = t9, lucus & master 2 = t13???
I don't see many players who clears regullary T13 and i see very few crafters in my world who sells regullary 4 star items.
