The chat box and chat on the screen just bugs me and I won't be using it anyway. Will there be a way to turn it off?

Can't say for SURE but of all the toggles in MMOs these days this one is very commonplace.

Probably.

You can probably turn everything off...

Lets say you didn't want to play in a dungeon, you can probably turn dungeons off....

You can probably EVEN turn off combat all-together.

You may even (now this is OUT THERE)...be able to turn off....wait for it..... the game.....

You have to work together in your dungeon/PvP group. And will you simply ignore people trying to communicate with you? How will you talk to anyone?
