I just played a long session with my friend and the one thing we both didn't like was that only one person got to see the normal dialogue/conversation where no decision/agreement had to be made. We both had the double/dual dialogue feature ticked in Game Options, and yet one person had to use the Combat Log to follow the conversation, but the Log didn't provide information as far as the lines selected, only NPC responses. In addition to that, the conversations/dialogues were interrupted by local NPC's talking about random stuff, which made it even harder to follow the conversation the other party was having. This is even worse when an agreement between parties had to be reaches because you can't even bring up the Combat Log to see the whole conversation when the Agreement-related selection is required....
At the very lease, there needs to be a way to isolate the actual dialogue a party member is having at the moment from all the local talk. The best thing would be for all parties to see the dialogue exactly the same way (as if both are talking) and show which lines were selected to the secondary part that is only watching.
Another annoying this is that its very tedious to switch from typing in local chat to pressing a button outside of it. Let's say I want to write "M" in local chart and I do. Then I want to press "M" outside of the chat window to open the map. That doesn't work all the time because even if I type "M" in local chat and press "Enter", then the next time I press "M", it will still show up in the chat window and will not open up the map.
Finally, I find myself having to click conversation choices TWICE instead of once when a decision between parties has to be reach in dialogues. I think NPC dialogue / conversation system for MultiPlayer sessions needs to be polished or even redone. It just feels unresponsive and sluggish instead of smooth.
Also, there were camera quirks here and there, even without enabling Camera Rotation.
Outside of that, there were no Host or Client crashes during saving, loading, level transitions, and etc.
I surely expect a LOT more patches coming out, but I have already found out that there are bug-fixes which would work ONLY if one were to start a brand new game and wouldn't work on already saved games. My friend and I started the game with 1.0.53 patch, so I really hope that patch made the game playable enough!
