FFXIV dungeons are a little bit too linear?

Diadem was probably an experiment to test out the viability of a non-linear instance and look how that turned out.

Lol, well thats a horrible way to do it. You have 72 people in an instance not working for one goal and includes gathering classes. No, its most certainly not a test for non-linear instances. -_-
