So, I've been trying to find a good breakdown of the minimum DPS you should be doing (I know, I know, build dependent) for the different torment levels. I can already do t1 and t2 4 player rifts fine (I'm critting about 2-3 mil on normal packs and 7-10 mil on elites with a blessed shield crusader, for reference). Anybody know a good baseline dps for the higher torment levels, or been able to find any guides with suggestions?

what do you mean by "minimum dps" there are players that clear T6 with less than 100k damage (no joke) its all a matter of efficiency to you. to you what is efficient. I honestly would focus on your primary element stat to stack up. if you have around 1M sheet dps and 75% elemental skill increase, you should be fine for really any torment. Then again like you said. a lot depends on the build and items you currently have. Currently if you want to effectively clear things it isn't a matter of increasing the numbers on your sheet, its more so increasing the effectiveness of your build with set bonuses/passives
