When it comes to the "echo buff" (or whatever it will be) that will eventually be added to turns 1-5 of Binding Coil, you mentioned parties will have the option of disabling that buff and running the dungeon as it is right now even after the addition of the Second Coil.

Will there be something added, say a piece of vanity gear, a title, or an achievement, that someone can use as proof that they cleared Binding Coil without needing that buff (I'm thinking similar to the achievements from 1.0 for defeating the hard mode primals in less than 10 minutes).
