From what I gathered.
Super Training has been completely removed from Pokemon Sun and Moon.
This I find really disappointing, as Super Training was a step in the right direction in terms of accessibility to online battles and Hyper Training takes the step even further.
But the removal of Super Training as well as the way to reset your EVs if you mess up on EV training, makes Hyper Training redundant what's the point in a perfect IV Pokemon this way, if you can't even get EVs done like in Gen VI.
Horde Battles are gone too, so you can't Horde EV Train either to get it done quicker.
Actually losing a bit of confidence in this game right now

EDIT: Triple and Rotation battles have also been kicked to the curb which I also don't like, they are both relatively interesting and add a different flavour to normal battling.
Now I have to convert my Triple Battle team into my Double Battle team, not going to go so great

. Triple Battles made my Archeops so strong.
more EDIT: Poke Pelago is the new replacement for Super Training. 4 EVs ever 30 min (15 min if you use an item found on the other Islands), so you now have to do a Pokemon XD Shadow Pokemon purification like system if you want to EV Train your Pokemon without using the traditional method.
