Not just SE, but taking that they tested and tuned content for granted is laughable considering the whole history of hard MMO content.

It's a complete non-point anyway since the function of a ilevel requirement is for the DF, you can do gear checks yourself in premades. Why would you want DF groups to have a harder time than pre-mades when they are overwhelmingly learning groups? Doesn't it make more sense to give yourself a bigger margin of error for random learning groups?
