nobody says there is a "perfect way" to counter the awp, there isnt a perfect way to counter ANYTHING in a tac fps like this.
but there are ways to mitigate the impact of an awper and reduce how much influence they have over the map. you can clearly see this in NA how TSM aren't able to win against t1 teams because they invest into wardell completely, but teams like sen/envy are able to nullify how much presence he has in the game. even if he has high stats/acs his impact is significantly lower, killing their win condition
acend are not immortal, they have lost matches and clearly show what happens when teams play around cned to shut him down. however it isn't just a one dimensional strategy thats just "Wow, lets just counter the awp!" it's a changing process that is increasingly harder against a player like cned who plays with a dynamic and active playstyle
