Add announcer voice for pings
Can you make the announcer do voice-overs for the pings; so if Nocturne is ganking and pinging 'on my way' the announcer will say Nocturne is coming top (this will help allow other allies to generally know what's going on to without having to look away) or if top lane pings enemies are missing the announcer will say "Enemies missing in top lane". Some other examples could be: "Ward here", "Enemy Ward here", or "Lets take dragon" if you ping dragon, etc. It's pretty surprising that LoL doesn't have this feature when so many other MOBAs do (ex: Dota 2, SMITE)...
Edit: Limit number of pings and add an option in menu to toggle this on/off for people that don't want to hear announcer. Rapid pinging should also not reset what the announcer is saying, to stop audio from restarting over-and-over.
