[IDEA] Pinging Enemy Summoner Spells

So this is just an idea I had thought of playing the game a little bit and I thought it'd be a good idea if we could actually ping the enemy teams summoner spells so that they were visible to you and your teammates. Now I know this sounds kind of unfair/unbalanced at first but hear me out. Once you see an enemy champion flash for example you could ping it within the first 5 seconds of witnessing it and it would be visible to the entire team as a summoner spell that has been used. Much like pinging your teammates summoner spells, just the other team's. This way you wouldn't have to guess when it comes back up even though you KNOW they used flash or ignite or whatever summoner spell they used. I guess I just feel like there should be a reward for players focusing on the game and taking the time to ping summoner spells so their entire team knows what's going on. This might sound kind of like a minor thing, not very significant right? It's actually quite the opposite, especially in high elo gameplay. For instance if your mid is in an intense 1v1 or watching the map or buying in the shop or whatever and they don't see the little notification that the bot just used her flash then that's a missed opportunity for a kill and win even. Another example as to why this would be useful is if let's say your Caitlyn bot DID ping that the Vayne had used her flash and the Kat DID see it but it was only after your died and respawned after spending a few seconds in the shop buying, how would the Katarina know exactly when the Vayne flashed or approximately how long she has until she has to gank the Vayne? The list goes on, thanks for reading this far if you did and be sure to comment about what you think of this idea,l maybe I'm missing something obvious and just don't know it but it seems like a good idea in my opinion... Thanks again for reading. ~ Inflatious

TL;DR: Basically you and your teammates will be able to ping the enemy team's summoner spells and be able to see exact cooldowns on them within 5 seconds of witnessing the action take place.
