Some friends and I were wondering if anyone knows how to determine what the baseline for magic find is now with Torment 1-6. Given the new gem drops, we were playing around with the idea of an extra 35% MF in a helm socket. If the base MF for, say, torment 1 was 300%, an extra 35% would be fantastic for farming. Not nearly as much if the base was more ridiculous like 3000%, so I wanted to know if anyone had an idea. Thanks in advance
You would need an insanely large amount of data to be even remotely close to figuring out that number - and it would still only be a rough estimate. However, just from personal experience: if you consider "Normal" to have 0% MF, Torment 1 can't have something like 1000% MF. In fact, even after the MF hotfix many people resort back to split farming on Normal because they don't feel any increase in drop on T1. I personally don't perceive a difference at all, actually. But it's just my subjective perception.
Also keep in mind that MF only accounts for 10% in terms of legendaries; even if it's 300% on T1, it would only be 30% for legendaries.
Between my follower and the topaz in my helm, I would say I have above average. Farming Torment 1, with and without it, I honestly notice no differences. In a single rift I did get 3 legendaries from the boss on Torment 2, after equipping the MF, several hours later. But honestly don't think It would have changed a thing without it. I did several more, maybe 4 or 5 rifts and got nothing also on Torment 2. My thoughts so far is, unless you play 4 people in a group stacked with a high topaz and nagel ring then differences are so little that it isn't really noticeable.
