I disagree. Crafting is now more part of the game.
Pre-2.0, you had all these low level legendaries that no one ever used because the time you spent between level 21 where you could first get a particular legendary, and level 31 where that legendary is crap compared to any level 31 yellow or blue, is so short compared to the time it would take for you to actually find that level 21 legendary.
Post-2.0, all of those legendaries can now roll at whatever level your character is, so you actually have time to find them and make them useful.
That is basically the same as here. The time it would take for me to grind out all of the mats for a particular crafted legendary, and craft it multiple times is likely longer than it would take for me to just find a better legendary on its own.
Now, with the buffs to class-specific set items, there's no way anyone would spend time grinding for legendary mats to craft a mediocre legendary. By making this change, they have turned crafted legendaries into something you can use right when you hit L70 as a way to access T1-T3 before you get the really good set stuff.
