I get in a match, and our Sova (whose IGN is Aqua) probably had some macro or whatnot, since he managed to spam a massive amount of pings ( he would spam the "weapon on the ground" pings ). This literally kills our team's fps. I hope Riot finds a fix for this.
This is being addressed in the upcoming patch by rate limiting. Additionally, in the patch after, we've made some performance optimizations so pings don't dip your a framerate when they happen.
Thanks for reporting! The best places for these are the bug megathread which we view often. New threads are actually more likely to get missed than the bug megathread. (as /u/PankoKing already noted)
