Aeon's hourglass

So I was considering the next build I might like to fiddle with and I started wondering about the hourglass. What sort of build would this constellation work best in. From looking at it on paper it doesn’t seem that impressive but it is a third tier constellation so that must mean it excels at something, right? To pick it up requires a pretty heavy investment.

I see it used for builds with long-cooldown abilities, like Doom Bolt and Devastation. That’s probably its best use.

It’s used for what are called “piano” or “cycling” builds. Builds that specifically rely on cooldown abilities ONLY. It’s not terribly useful for packs, because it only takes one or two to kill a pack, and usually these builds have five or six skills on cooldowns. In boss fights, however, it shines, allowing a double tap on many powerful abilities.
