Stop Abusing the "Enemy Missing" Signal For Questionable Plays!!!!!!!
You don't realise how badly this messes up your team. While you're spamming that shit as an ADC to your support for his questionable hook ,or grab, or whatever, as a jungler i'm thinking "oh, you see a gank incoming, I should get down there" only to realise i wasted 30 seconds going from the top side jungle to the bottom on to see your bot lane backed to base, and that no enemy ganks were incoming at all. Or maybe I will be mid and the jungler will spam it to the top that decided to risk it, and tower dive and now im thinking "shit my mid is dead or backed and you need help, here I come" so now instead of farming CS and putting damage on that mid tower im on a wild goose chase to try and help a bad situation that isn't happening. OR.... Maybe i'm the guy with those bad play's you don't like and you spam that on my lane as a mid and I think "oh your mid left and he is heading for me, better hug my tower" because i can't tell if your trying to warn me or give me shit.
Seriously, just use the chat box, because there to many ways someone can interpret that signal. It doesn't just affect the player you alert, it affects your entire team. Be smart about how you use it.
