Since the new patch, I think SE has done a pretty good job of separating those who want to challenge themselves with tough content (second coil) and be rewarded for it, while not completely excluding the casual players. The new solidery items and echo buffs gives the casual players access to new higher lvl gear and doesn't exclude from now completing content that was previously too hard for them (T5 and primal exs). Secondly, the new coil turns are the only way to get sands, oils, and unidentified allagan tombstones to up grade those solidery items to 110. This will still allow those advanced players who busted their ass learning the new fights to have a sense of accomplishment.
