The problem with multiplayer epicness is, there are thousands of players wanting to build their characters to epic proportions. Which is possible only if we see one's relative progression lvl1 to lvl50 on an ever raising exp curve.
If everone is eventually epic, then noone is. This is because of the eventual fading of contrast, and the environment leveling with us. (well if we keep the challenge factor in mind) (No it is !not! epic to go spam newbies to duel with you)
In single player games it is easy to direct an epic scene, because it only has to be proportional to one perspective, one player that is.
I would like to see Epic coming to MMOs as well, and to ESO of course.
Sure there are a lot more scenes, some that felt really unique.
