Some of Sage's wall are creative and cool but you can't hear them from afar unlike jett's updraft+ult, and that can mess with the counterability of those angles, since they're not your normal part of the map off angles. You also can't hear it well if it comes down unless you're very close. After the update it disappears faster with no cracks to indicate the time, which can sometimes get you killed. Also it appears if you use the jump crouch mechanic, you can still use the removed teammate body boost which can get agents with vertical mobility to gamebreaking spots out of the map. Tho, I don't wanna see jump crouch removed rather more changes to hitbox.
