setup crossfires to punish the waylay pathing, she has no util to create safety for herself, she has to dash into areas of the map that are safe for her, more like a raze than a jett, the pathing isnt free form its set and dependant on the map geometry, so you need to position to force her to "recall" insta and then have someone setup to counter the punish from the yoru, combine that with strong stall util to stop the rest of the team and util to fight with like vyse flash you can 100% stop a full waylay exec, once you have proved you can do that you force the other team to play midround WAY more since they have to find weaksite because they know your strongside can stop their execs, this means they are more punished for waylays relative lack of util compared to many other characters and you can force them to expend what would usually be exec util to take map control and try and force rotates, which means their eventual exec is weaker and much more manageable even if you arent in a dedicated setup to counter the set exec, if the waylay has to expend dash or hinder to take some map control then your anchros can be told this and then then know they can position differently because of that.
