My budget gear 211K beats diablo.
rings: 27570 + 5500
Plus regular flawless square gems (the ones you pick up in inferno)
Additional rule I had blue items only.
See full gear in my profile.
(sorry I tried making a video, but my comp couldn't handle D3 and video. we don't all have gaming computers).
Bottom line: Blizz, please make this game challenging.
Edit: yes this is inferno mp0. So what? Are you supposed to be able to beat diablo in mp0 without any good gear? I can otherwise do mp8-10 no problem, and don't have godly gear like some other people. I'm 150k dps, SNS wiz, 2.74aps, 53cc, 800LOH, 780AR, 4.3 armor, 40k HP etc. etc.
The point i'm trying to make, in a game that's all about the gear, you don't need gear to beat it.
