Yeah, I could get something fully EV-trained in under an hour in B/W2. With the aid of EV training tools (like http://zero456.com/ev-counter/) to keep track of EVs, it was mainly just a mindless chore. I could watch netflix as I was doing it. Super training has required more attention from me so far. Or atleast, requires me to do more than glance at the screen every now and then.
But yeah, I agree the old way is unintuitive. New users only interested in playing the main game probably wouldn't know about it, but if you spent any amount of time around the competitive battling community, it'd be pretty apparent.
I just wished they changed IVs in some way. I'm very glad Pokemon from the friend Safari comes with at least one perfect stat IV, though.
