I emphasize complexity over difficulty in the sense that we really shouldn't see content where only the smallest fraction of the playerbase can hope to finish. Being better geared could help finish more quickly and safely, but the moment you basically introduce the equivalent of "gear checks" that other MMOs have, you start alienating people who are either unlucky with drops or simply don't have the time to hunt them with any level of expediency. Now, this isn't to say people wearing level 1 RSE should be able to beat everything, but a little bit of common sense should go a long way.
