The devs didn’t even acknowledge in patch notes that it had been removed, let alone give an answer for why it was removed.
Here is the thread I made asking them why:
As you can see, 100 likes, it seems people would like an answer, but no posts in this thread as it isn’t about skins or something fun.
I totally agree it could be misleading, but no more so than self healing, which doesn’t even display for some heroes. Both metrics can be misleading, can be used to flame teammates, but for me, I think the more information we have the better.
