Scratch that hopes of my backpack

 Ummmm yeah..... So I feel like a complete idiot. Turns out I failed to read the details on my Dragonscale backpack. Yeah, so I hit 5000 corrupted mementos, HOWEVER!!!! I failed to read the fine (actually hard to miss RED print) that I needed get an achievement first... WTF!?!?
"We Have the Technology" achievement needs to be completed first... well what the fuck do I have to do now for that one? 
I have to complete whaaaaat??? are you fricken kidding me!?!?!?
I was so sad and disappointed I would not be getting my backpack anytime soon.

I have a crap ton of Coalescing visions and Echoes of Ny'alotha to buy the Vessels of Horrific visions so that's not the problem, but just having to run the horrific visions over and over again to get all the mementos I need to complete the Research tree... THAT is my problem. 
Lets do some math shall we:
3300 mementos x 8 more researches to complete = 26,400
26,400 ÷ 800 (average mementos I can get per run, no full clear) =

  wait what??? over 30 runs!!!... no no, fuck that, I have to do full clears now. I don't know how to get or do mask runs, so that's no bueno. Well shit, looks like I'll be farming some Visions this weekend. At least it's a long weekend for me. And I need to do this now since I start school in a week and a half, so I might be slowing down if not fully cutting off my WoW time.
Alrightee... Wrathion, here I come!!!!!
