Other classes need a leg up from some external power to be strong: shamans ask the elements to help them, paladins shine their flashlights everywhere, DKs go to edgy death magic boot camp and DHs wouldn’t shut up about how they sacrificed everything for [fel magic] power.
Warriors just get so damn MAD that we demolish entire mountains with our own might. We don’t need to get juiced up by magic to be able to do that - let the weaker classes have their much needed clutches to be able to get to our level of power.
Warriors are simply men and women. Ultimately, they are the most basic fighting unit you see, yet they are the first on the front line. They don’t use magic, call to the Light, charm pets, or summon the elements.
It is just them, wearing poorly fitted armor or carrying a weapon to heavy or light for them to wield, defending the world from worst monsters imaginable.
