Getting to Atziri/Uber Atziri

Atm the cheapest midnight sacrifice fragment is 10 chaos.

Is it likely to be worth actually buying in order to run? I seem to be able to get the other three fairly easily, but I can't seem to get the midnight one.

Currently the cheapest I can get to Uber Atziri is
Mortal hope 4 exalts
Mortal rage 3 chaos
Mortal Ignorance 10 chaos
Mortal Grief 2 chaos

So basically 4 exalts and 15 chaos just to try Uber. I stomp regular Atziri usually without any death at all and I'd like to try Uber, but the price to do so is wow. Looking at the price of the armors and stuff, it seems like it is throwing good money after bad. Isn't it?

So is this Working as intended? Shouldn't the drop rates be adjusted such that players could actually experience the content rather than just a select few farmers? Should such a large feature be so cost heavy that it is not worth doing or such a time expenditure to even try?

Obviously GGG don't control the prices, but by control of the drops they sorta do. Is this really what they want or do they just not understand?

Best way to kill Uber Atziri?

Reroll to Perandus league and lol at the prices there. 45c for a mortal hope.
Worst league ever -.-

That is by far the easiest way to do it. Getting the gear to kill her shouldn't to long for someone who has done it before.
