i think voice in the tower would be real nice. you meet new people ask if people wants to raid. i think the way PS Home did it was good. i never really got into PS Home but i think the voice chat was cool like holfing a button down to talk to that one person. or maybe a little note saing RAID? on top of the heads of msybe in the when you inspect somebody . to let people know what you want are looking for. becaues im trying to raid and hate to use the ps4 chat it takes to long to load up and write back.
