I believe the pings could use some updating:
The menu list is long. ‘Stick together’ and ‘Let’s teamfight’ to me are the same. Pick one, remove the other. I don’t think ‘Sorry, my bad.’ is necessary either. The sad emoji works for that just fine. I would also love that if you ping an enemy hero, similar to how your hero’s face and the emoji shows up on your teammates’ screen, when you ping an enemey hero, something like “focus [image of ringo’s face]” shows up on your teammates’ screen. That way they know it’s not a trolling ping, in-case their camera isn’t in the same spot.
You save two spaces on the drop down menu, and the pings get more meaning. (green could signify focus, caution could signify don’t focus or stay away from…)
