Yup. Exactly.
But its unclear to me what is happening in these conversation exchanges.
1)  D&D Fighter 
closes to melee with the dragon (a prerequisite to deploy their atttacks).
2)  D&D Fighter deploys their attack(s).
3)  D&D Dragon deploys their melee suite of attacks onto D&D Fighter.
4)  D&D Fighter 
somehow survives.
5)  Rinse and repeat until D&D Fighter 
somehow slays the D&D dragon.
I'm not "cancelling anyone's opinion" and I'm not calling people's play badwrongfun (but I sure as hell have had that called against me aplenty in the past!).  What I'm curious about is (and I would love if you would answer this 
@Micah Sweet ), given the above 1-5 and the bolded/italicized in particular, 
what is happening in the shared imagined space to make this true if not D&D Epic Fighter's athletic profile reveals supernatural explosivity (omnidirectional speed, strength, agility), endurance, coordination, proprioception, and processing speed/efficiency?
