@massivelyop I don't like the "endgame" concept because what's endgame? level cap? raiding? at which tier? Are dailies endgame?
Plus, I like MMORPGs that are about the journey (#LOTRO, #TSW)
That said, I liked the #GW2 approach that let you experience some of the "endgame" content (mostly the PvP/WvW experience) while still lower level (I did most of my levelling there...)
