I dunno. I mean if you have everything else you want it is kinda worth it. My DH has 15k HP now from vital infusions on my ascended armor/trinkets. that's absurd for Guardian. 

All of my infusion slots are full of agony resistance. x_x The only way I can add power is to make those expensive things. But the fractal mastery does have a vendor that lets me extract infusions for 24 silver per piece of armor. I've used it so many times swapping AR around. I made sure to save my +20 exp and +20 magic find infusions that I bought with laurels. If I can finally put high level fractals to the curb I'll swap some of this AR over to power infusions and save the AR ones for a rainy day. I really wish AR was an account bound upgrade thing like a mastery and not tied to armor slots.

Yeah I use vital/power. It's a great boost for regular dungeons.
