MIA ping is being used more often in games to flame than it is to actually call MIA

Can we please change the symbol on the ping? It's being used more often to flame your teammates than it is to actually ping a missing enemy. It's very distracting and you can't mute it without muting the whole team's ping volume.

So just today, I played a game in mid. Our Jungle comes and ganks and dies. Shortly after, my enemy laner goes MIA. I ping MIA, and our jungle started to flame me. At first, I was confused, but then I realized he had misinterpreted my ping for "wtf, why did u die jg?" The confusion was quickly cleared up, but the fact that I had to explain myself really annoyed me and reminded me what the MIA ping has become.

So not only is this issue very annoying, but it also confuses players because they have to try to distinguish which is an actual MIA ping and which are just flame pings. Please change the symbol on the ping.
