As a new player coming from Path of Exile, playing with a friend that is also new for a couple days now, we recognized an issue with chat and lacking chat options, specifically in this case:
- Going to or from town to a different area sets the chat to “global” automatically.
- Missing or no meaningful chat options to make adjustments in how the chat works.
The reasoning is that in a coop scenario, I don’t want to have to change the chat setting to “party” or the like every time I went to town even once. I often shared items or wrote things in “global” by accident, and having “global” chat hidden, I don’t realize every time. It is very annoying.
For comparison, in Path of Exile Chat, beyond hiding chats you don’t care about, you can press “tabulator” while the chat is open to change the chat type you use, and of course, the chat type doesn’t get changed at all unless you log out and in.
I haven’t seen mentions of this in the forum for feedback in a quick scim through, or in the patch notes that came out just a few hours ago, and got no solutions from questions to players in the game. That’s why I hope for some replies that can tell me there may be options to solve this, otherwise I hope this automatic “setback to global chat on town visit” gets… changed 
Looking forward to cycle 1.0!
