QOL: No disrespect intended, but...
you are in the group of the stupidest people to play League of Legends if you sincerely believe that 1 missing enemy ping in your own lane is good communication between teammates.
Wards are no longer dependable. As a top laner, I know to keep my eyes open for the enemy jungler's position. What I'm not looking for is a mid laner or support to be top lane. Then you justifying my death because you "?" pinged your lane one time 25 seconds earlier while I'm trading in lane.
I insist everybody start using my method of communication. You're allowed infinite pings to communicate, or 5 spam pings. 1 Ping enemy missing in your lane 2 Danger/Warning ping other lanes and jungler 3 missing enemy ping their last known location to you (may be their fountain if you know they recalled) 4 Danger/Warning ping other lanes and jungler again (especially if their ward vision is gone)
All 8 of those pings takes me about 2 seconds and I know my team is fully aware of the threat
