I think what others are trying to say, which I agree with, is that throughout these forums players have suggested implementing optional commands in order to compromise the different player types, but really these options are forcing some to use "X" feature. In this case however, I don't see that being much of an issue, as I can't see anything being shouted or what have you that would necessarily be important or put anyone at a disadvantage, at least more so than what we have now.

Concerning people abusing the chat, unfortunately that's going to happen, but players should take it upon themselves to be courteous and actually post in the right log if there are multiple channels. If people use it correctly, I feel others would be inclined to follow by example. Perhaps constantly using the wrong chat will cause a GM to step in to help put things back in order.

With all that being said, a greater part of me is still against a global chat and would rather them adjust and expand on the features we have now.
