Just remember there's no requirement to do roulettes for Esoterics, and they just increased the alternatives.
Raids, pvp and now Diadem are all options, so nobody is actually forced to keep doing the same dungeons.
Completing any 3 objectives in Diadem awards 40 eso, every time. Also a chance of i210 better than Eso gear, and unwanted drops can convert or exchange for materia.
