I was just wondering who uses this ping (the "on my mark" ping) because I can think of soo many other options to replace it with, like "on my way", "smoke", "wait", or idk, others...The thing is that I've hardly ever seen anybody using it,...

Can someone help me cause I tried the 'equip last used item' in the options but it brings me back to pistol and I still need to scroll down in order to switch back to op after getting a kill. I watched some streamers and they barely switch...
