Change the yellow ping to fall back instead of becareful please

The fall back ping long time ago was so good, people listen, now when I ping yellow, people really think I mean to just becareful when I actually mean to fall back. We also have a red ! ping that means danger, so there's no point. So why have 2 pings that means the same thing? So please change the ping to fall back because I hate spamming the yellow ping and my teammates still going in at it and dying, thanks.
