Why late game oponents start so weak?
Why do I have to level up to 4 stars (6 battles) against (21 oponents) before I actually have a challenge against the AI ?
I understand early oponents being weak but why the late game ones start at 1 star link ?
It actually takes 120+ battles before you can actually have a challenge
Good luck on the grind if you didnt pick red and need to sit through slower matches
