Wheel-less general ping or setting to change the wheel's threshold
The ping wheel that's used to select a specific ping is useless to PC players who have taken the time to bind all the specific pings. For them, it's more of a hindrance than anything, because the wheel tends to activate and replace the general ping when you don't want it to.
I have had this problem a lot, as did my friend, and I've noticed a lot of people using a wrong ping like pinging an enemy when trying to ping loot. I think most people have encountered this at least once.
I suggest two solutions : either give us a general ping without any wheel, or give us an option to tune the threshold at which the wheel appears. This way players can use the general ping without having to stop moving their camera to make sure that it won't activate the wheel.
