It is definitely tougher, but the only thing I'm really frustrated about is that I keep losing to crits. :x DynamicPunches from Gurdurrs hit multiple times in a row, some pokemon can toxic + protect for several turns without fail, just crits in general are making the game pretty frustrating.
Also, has anyone else noticed that the trainers suddenly jump in levels? Like there will be Pokemon leveled mid-30s then all of a sudden they'll all become low 40s? Or the main storyline's last battle has Pokemon leveled 50, but then the Champion's are lv 61? I hate grinding
