Channel chatting.
Firstly the reason I thought about this is when I entered boss and decided to say hello through the channel chat to see if the other player would answer, I was surprised to get a answer and had a nice chat to bull007winkle. After the battle I was a bit disappointed about not being able to see him chat again until we get lucky and do boss together again.
So the way this works is in pvp we will make 4v4 rooms named 'channel chat' and then you get people in your room (not for pvp unless everyone agrees I guess and make sure you don't press ready if you don't want to pvp). Hopefully everyone will start doing this and we can get to know others without having to get other apps to communicate. (:
Note that I know a lot already know about this way to talk.
Another note is try using it in boss and pvp to help each other and not get confused on to who to go for.
Have fun y'all and hope to see you in a channel chat some time soon.
