A few ideas of how to save D3

[Roland]

I would really like to be able to create a game with a personal title (public or passworded) that my friends can specifically join if they want to or if I invite them.

Your friends can join any game you are in so long as you have that option checked (or unchecked, I forget) in your options. Otherwise, only people you specifically invite can enter your games. Short of being able to make Public games with specific titles for specific intent (i.e. Trading, Azmodan runs, whatever) there's no need for the function. The current implementation is miles beyond what D2 had to offer, and for the better.

The chat system definitely needs work. I would love to have te ability to join a global channel similar to /g in WoW where you could idle while killing things. Chatting with friends kept me playing WoW longer than I would have otherwise and I think it would be a fantastic addition.

They have a general chat channel like in wow. It's called /General. Look in your chat window when you first log on or create a game. It's right there in a big hint.
