I don't get it, people are saying Dark Shadow build left and right, including Riff's guide, but all the data on WarcraftLogs pretty clearly shows a Shadow Focus - Enveloping Shadows - Master of Shadows build to be better on single target. Those talents are on average higher than their counterparts on virtually every fight:

You can see the same if you look at the top 100 Sub parses on most fights:

Am I missing something? Dark Shadow - DFA build seems more complex AND performs worse. If you look at some AoE fights, it pulls ahead, but as far as I can tell, people are recommending it even on ST. Riff doesn't even mention Enveloping Shadows at all in his guide, only listing Dark Shadows and Alacrity as viable options.
