Your ping should be made known to your team.
Not the enemy team because that will result in bad things. If it's known to your team it will resolve a ton of conflict in game. Same with your FPS because that's basically the same thing.
It would really help with those people that say you're trolling in-game while you can't even see what's going on. It would help me because yesterday I had a Blue Screen of Death which raises my ping by like 1000 forcing me to play normals and still feed and get called a troll.
