"nobody pings in high plat, even during laning phase"

I don't like players who make excuses for not pinging. The ping system is such a helpful part of the game, and using it makes you a much better teammate. I constantly use the mia ping for any lane I see missing, retreat pings when I'm not going to be fighting, danger ping when I know enemies might be collapsing in on allies, destination ping when I plan to go somewhere, etc. Sure everyone should be aware, blah blah, but not everyone is, and everyone has had many times where they tunnel visioned or didn't see a teammate fighting and dying, or didn't see that gank coming even though you saw the enemy coming from the other side of the map, etc. It's a team game, the more you do to help your team, the higher your chance of winning. The ping system is like a second language to me.
