I am watching DC vs 4Clovers:

While the Slark does some amazing plays, it is too bad he goes for the stupid shadow blade build. I watched the BananaSlamJamma video about Slark (the 3h23min video) and I have put it to test, it is definitinely much stronger to skip Shadow Blade entirely. Edit: Okay, it pays off in this game, PA is getting ganked.

I would not say it has increased my winrate with Slark (I was 55% and I am now 60%) but the laning phase and the early-mid game is much stronger without Midas and Shadow Blade. Of course, this statement only applies to 6.84.
I am also watching that from time to time.
