Binding Coil was released when the game first dropped on patch 2.0. It was all the other stuff like extremes and the big relic grinds after that.

That being said, the only place that does demand perfection, is for the most part, ultimates. There can be a few mistakes that are possible in the eariler ones due to power creep and potency changes, but take Dragonsong for example. You can't really screw up at all. Screwing up strength is a wipe, messing up the second half of sanctity a wipe, a mistake during dive from grace/enumerations, a wipe, a mistake on death, a wipe, dying to hrae, a wipe.
