When auto-Legendary kicks in to guarantee your drops, don't pick them up...

Wow, I'm really glad you brought this relevant comment to the discussion.
Meanwhile, people over at the forums seem to have figured out some interesting things.

I have noticed I get same legendary amount on torment I than III on 3 accounts. I've noticed I've got as many legendaries afk farming in normal as in torment IV. I didn't notice difference in chestruns in t1 vs t6 either, always did them in t6 tho because of "why not", but still had those moments when I've opened 150 chests with 0 legs in t6.

I'm return to d3 from start of RoS, and observe following pattern: Drop 1-2 legendary items within the first 20 minutes after the break in the game (woke up in the morning - loot couple; back from work, and in half an hour - another couple).
And i really didn't see any reason(except new set items of course) to run anything than normal - no drop rate increase with higher torment difficulties(in terms of leg's per run). All what you get instead - drop rate decrease in leg's per hour.
In my opinion, the best way to get legendaries - passing on the level of difficulty, which is limited only by the speed of your running speed => which leads us to normal or torment 1.
Certainly the situation is somewhat different with the game in a group, but I dislike it =(
Excuse me for my "google translate" language.
