>>29918507well, I've been running around with the Exp Share off and not grinding and raising 10 pokes and I started to drift away from the average enemy level by the second island.
I'm like almost 8 levels below ya boi (his mons are like at 43) right now, he actually rekt me 2 times. I noticed I used way more items than I usually use, and been bailed out a couple of times by the amie boosts (I forgot you recieved boosts for petting the pokemon and now it's too late). Some totem fights are kind of a bitch too.
Using the same play style (no exp share, no grind and many mons at the time) in gen VI was way easier, so I'd say there's a big improvement
