We don't want chat bubble it will make the screen look messy and having that option of turn on and off is rather pointless because when that happen you will see all the /say chat spam all over your screen because people will be using that as a way to chat instead which either you will end up in blacklist

As for party/raid how about No?

Surely you don't want poop ton of chat bubble in the middle of the fight with their Marco spamming all over your screen
