I believe that it was mentioned in the BlizzCon press interview that they are experimenting with the idea again, but there are no definite plans at this time. Originally, Jeff Kaplan did say this earlier in the year:
Respawn did such a good job with the Ping System in Apex Legends. It works really well.
Back in early development of Overwatch, we actually had a very similar ping system. Ours was inspired from MOBA’s like League of Legends and Heroes of the Storm.
We eventually removed it because of a few issues.
With 6 people on the team, it got very spammy if more than a few people were using it
The geography of Overwatch maps as well as the engagement distances is fairly constrained. This made pinging upwards challenging and often frustrating. An example is standing at the gate of point A of Temple of Anubis and trying to ping the upper ledge above the gate entering point B. Our engagement distances tend to be in the 10-30 meter range (for perspective it’s about 45 meters all the way across the entire dojo in Hanamura B). In Apex, you have very long engagement distances and very big maps… it makes it easier to ping below you
It would be fun to revisit the system and see if we could make something like that workable. We do have some designs for improvements and customization to the communication wheel that we’re trying to get in. But we’re always appreciative of feedback and suggestions.
