I don't mind the odd callback theme, I think one of the more common ones we've had over the expansions has been from the Coil of Bahamut, as well as Everywhere and Nowhere.

But thinking about it, you're absolutely right--there's too many of them being reused too often. I think we sometimes hear them more than we did in their original expansions, which kind of cheapens their use as a whole as well. It should be a big moment when we hear one of these themes again, if not a direct callback to something or someone from that time, at least something that resonates with the scene in a similar way. The reusing of the coil's theme when we the WoL travel the rift and see echoes from time, I thought, was a good example of how they properly did this.

At least Arcadion gave us four unique tracks for the fights. That was a nice surprise.
