It's not a bug. Thanks for reporting!
The pings still being on the minimap is a bug.
However, if you've been checking each update thread, you'll notice that alot of people have already agreed with me that ally taunts should re-added anyway, can you please bring that up with the other devs?
Take a look if you don't believe me:
Re-add ally taunts
OH YEAH. fix this. Thanks
There was no reason for this feature to be removed, it's been in the game since release and suddenly deciding to call removing it a "feature" because a bug broke them in an update is not okay. And as you can see here, there were numerous people who enjoyed it and would like to have it back in the game.
