A small while back I made a big thread on here and reddit with a laundry list of videos showing the tp selfdestructing on invisible geometry. It got a good chunk of traction on reddit which is why I assume it was noticed.
How do I know it was noticed?
The next patch, they fixed the location that I showed as the first video in my list. Just the one location lol.
The thread: https://www.reddit.com/r/Overwatch/comments/qm0il8/in_case_you_guys_didnt_know_syms_tp_has_had_a/
The first vid: https://www.youtube.com/watch?v=itfosNjo4Xs
And next patch:
Guys, the point was to actually fix the ability, not the one niche case.
