"the quality of cs shows it" sorry mr. punctual i didn't elaborate.
1. Communication is at an all time high, as told by players themselves in interviews.
2. Teamplay is way better and aligned- flash pops work way better, trades happen more efficiently, better calls from the IGL.
3. Individual skill has improved. We have a whole month of data to back this. Grim is performing way better, so is Hallzerk, Fang and Grim.
Ignoring all of this is just delusional. Also other pro players are talking about complexity and acknowledging that they have improved a lot.
