It’s still faster than it has ever been, ever. I got my 4pc day one, because I was lucky (One piece catalyzed, one piece for free from AotC, two pieces from raid).
Full tier set week 4 with 0 raiding, 0 dungeons, 0 PvP, 0 luck, 0 achievement is by definition free gear. Want it faster? Do PvP. Do M+. Do Raids.
