Understand that Coil may have the 'best' drops (best being subjective, there's some Dreadwyrm pieces that are only good for iL) but they were released months ago. In a game where gearing is the goal you can't leave people to get left behind. Especially with Heavensward just around the corner. As such, Square gave everyone the option of an alternate means of gearing in the form of tome and crafted gear (some of the iL 110 crafted gear is by and far better than Dreadwyrm, and that's before materia). This sentiment that Coil equivalent gear should only be obtainable by those who can complete Coil is entirely selfish and shouldn't be promoted to any degree. "You aren't the only hero."
