If you want to feel "epic" mmos are not the medium to be in. single player games are where u get to feel "epic". Since in mmos there has to be a level playing field and being able to "one shot" other players might be too much(ya think!). That being said from the other things you have stated it may be that pvp is what you are looking for. No complex fight mechanics and just kill them before they can kill you kinda thing.
