Are they worth it? Since there is no global chat, from what I understand, voice chat is going to make you appear on the list instead. That seems pretty useless. Most people I know are in parties when they play, so no one is talking in game, and any troll worth his salt is going to have his mic muted, so the only people that are going to show up are the newest people to the game.
Now I would love a global chat, would also love it if people were decent enough to hit people while they were online, but since neither is likely to happen…
I just don’t think making the change on a system with no global chat makes sense.
