To OP: There is a huge difference there.
Standard MMOs are WAY more complex than Elite: many more abilities (Like 30-40 on an average MMO at max level (some that do vastly different stuff than others, different skil trees, different classes), more interesting quests (if only barely), epic Boss fights, crafting, different roles in combat (healer, tank, dd , disabler), meaningful progression towards an end-game... all in addition to the grind, so it becomes more bearable. And near max level there is some sort of pretty hard end-game that takes a while to get the hang of but feels quite rewarding if done right.
Furthermore, that's not what I want a space sim to be like. It just wasn't advertised as the standard MMO experience. Multiplayer yes, but a standard MMO? I would never have bought this game...
I am not defending the grind in MMOs, I am just stating why Elite is worse... I actually have come to hate the MMO-way of playing. It's that Elite does it even worse than your standard MMO due to the lack of options and that's a real shame. Trading. Shooting the same type of enemy (either conflict zones or bounty hunting or pirating). Mining. Exploring. And all of these get easier the higher "tier" of ship you go, because no System is harder than another, there is simply no variation to this recipe.
And that's all there is and each one can be experienced to it's full extent in maybe 1-3 hours, trading in a lot less (including smuggling, rare goods trading and the standard trade run).
