1. Way too much handholding/railroading.
2. GF still doesn't know how to balance exp. You'll run into stark level differences one way or the other with Share on or off.

4. Calling for help makes trying to catch wild shitmons an immense pain in the ass.
5. Z-Move cutscenes take an age and a half, and you CANNOT SKIP the trainer animation even with Battle Scene turned off.
Bonus: All the new pokemon that people might actually want are hidden behind garbage encounter rates and massive quantities of Kanto pokemon.
All that said, I still like it more than XY.
