Rogues Glintstone set ..

[Jazzi]

The mythic set's piece order is like that because it's an artificial time sink. The higher the lack of meaningful content in a game, the more of those time sinks you'll see (eg. jewels). It's common sense that most people would solely go for helm and armor if there were such an option available.

"lack of meaningful content" is spot on. This season is full of artificial bottlenecks for gear, which is not even worth it. Even the events are not very exciting. The only reason the forum is not full of complaints about the Halloween event is that they at least gave us a new mythic weapon (smart move there).
