Currently there is a thread going on the official forums called “no world chat?” The thread is all abut how the chat system is going to work in Star Wars: the old republic . Normally threads like this is all pure speculation, but today Lead Systems Designer Damion Schubert choose to give us some new goodies.
Each planet has chat channels that allows you to communicate with other players on the same planet. Yes, we have different channels for general, pvp, trade, etc. You will be able to turn off the channel, flag another player as a spammer for Customer Support’s review, and ignore problem players.
Disregarding whether or not they are realistic (and the presence of technology makes them much more realistic here than in fantasy games – you only have to look at a CB Radio for an analog), chat is very good for the community. Of particular note, some of our best content areas are the awesome multiplayer fights our worldbuilders have been setting up. If to fight those, you had to go to town and wait for someone else to wander by, life would suck, and this content (which I want to stress, in my opinion, is usually wicked fun) would never get done.
We currently don’t have any global channels that cover the whole game. General rule of thumb in an MMO is that if your chat channel has more than a certain number of participants, it becomes spammy and unusable (something that we’ll be keeping an eye on in our earlier planets).
Damion also provided some insight as to companion options and Crew Skills in a thread entitled Crew Missions: Emergency Recall:
Currently, you can recall your companion at any time from a mission. You lose any progress he has made, as well as any upfront costs, but he returns immediately. This may be adjusted as we test further, but it seems to offer a decent balance.
You can also have a companion stop crafting an item at any time. In that case, you lose no materials (but all progress will be lost).
All pretty interesting news, as it tells us there will be some risk involved if you send a companion off on a crafting task or mission, and decide later that you need him back.
