A long time ago ZOS talked about adding more quick chat options (lets face it Zone text chat is never coming), but nothing new has been added. I for one would like to see a few more options added or be able to create your own.
For me the top thing I would like to see add is:
Can I Join your group?
The current "Group Up?" chat phrase ends up saying "Would you like to join a group?" making it seem like you are asking others if they want to join you, when you really want to ask them if you can join there group. This is a big problem when trying to find groups in cyrodiil as most people use group chat and not area. So it would be nice to have a different phrase you can say. Right now people use the "Would you like to join a group?" phase and then quickly add "Yes" to the end off it, indicating they want to join a group. It looks like a bunch of crazy people talking to themselves.
If you could see one phrase add to the quick chat what would it be?
