Communication Lacking

I am currently trying the ps4 version of the game, and i have noticed a distinct limitation to coop in the communication system.  I have found that no one uses the in game voice over option and we are left with just pinging furiously to get other players attention with no way to convey what the pings are for.  I think this could be improved in a couple of ways:

display pings on the minimap so that the other players do not have to look around to find where the sound is coming from...

give us more types of ping such as:

build here

sell this

defend here

and each ping could have a different icon that appears on the minimap to convey the meaning.

fyi: in the current PC version of the game, pings are as you desire:

CBT is "Build tower here!"

CQ is "Upgrade towers here!"

CZ is "Sell towers here!"

there are more... I imagine you'll get them eventually.

Yup! I'm sure it's frustrating to not have different pings on ps4 yet, but they are on the PC version so don't worry, they are coming in the future!
