I only saw the end of Boston vs Atlanta and all of Shanghai vs Gladiators. While there was still some GOATS, it wasn’t played all the time, not even close. There are maps like King’s Row where it is still played, but then again it was always a Zarya/Rein map.
I think it will be played less as the stage goes on, but it won’t disappear totally which is fine. It will be more map specific. Right now teams know how to play GOATS they been doing it for the past 6-9 months, it will take a while before they learn to master new stuff.
It’s a step in the right direction for sure though.
