Abilities and Items that are lacking ping information to the team
There are a bunch of items and champion passives and moves that lack ping information that can really help give fast information to players. I will try to list some of the moves and items i can remember that lack ping information or should have one added to help with fast information since most people do not pan the camera or use F2 to F5 keys.
Cannot ping the CD on his ultimate but Mega Gnar can but the thing is most people who play gnar will use their ultimate the instant or few seconds after they have transformed which can lead to miscommunication to team mates.
If an ally kled loses skaarl against anyone its really important you know about this immediately because if you ignore him he is going to become the easiest champion to gank. I've had my share of bad games with this champion and seen others lose skaarl and it wastes my time to type "Kled lost Skaarl becareful and watch him please" if im support or kled himself. I've said information like this and it has convinced mid and jungler to assist me in bullying or killing the enemy top laner either way he can get back on track and get his money.
Relic Shield
and Targon's Brace
don't give ping information on how many execution stacks you have left.
Some matches I've had an adc ping me to execute a cannon minion but he doesn't know that i already used my two stacks earlier to heal our butts. So just add that in.
