I'd like to bring back a request that has been forgotten recently.
Can we get more pings? Maybe a "this is warded" or "please ward here" ping would be nice for gameplay and quick and simple communication with your team. An "engage" ping might have uses too, although target pings and "on my way" overlap that.
Anyways, what I'm trying to get through is that having more pings would players coordinate with your team and would improve gameplay, along with overall fun.
