I have, always.
In 1at/2nd Ed 10th level + was huge, same in 3rd Ed, it just released that absurd ELH.
I do not need a bigger modifier added to my d20 roll to feel epic play.
I don't think any of us do either. But the ability to destroy anyone who is of lower level, handle scores of high level creatures and be on par with the big names of D&D is what most consider epic. And you won't be able to handle the pit fiend patrols of Nessus unless you are there
