Ok, not much said that I like.
1. Yet again you are putting crafting items behind group play. As such have zero interest in Feast of Prosperity, well just won't take part.
Going back to refresh older planets/pieces of content to make the gameplay feel better.
2. Updating older planets, Oh so now not only will the new planets be as laggy as hell you are going to make the entire game laggy as hell?
3. While I have no issue myself when we get new story I do agree with what others have said, you need to define holidays.
4. Echoes of Vengeance is about the only thing mentioned that is of any interest to me, however as said new planets are as laggy as hell, as such with anything from Ossus onwards I can only stick any part of the story for about a single quest. Now you intend to make the entire game as bad!
5. Craft changes? well, cannot say This is good or bad. As I am not going to assume any change is going to be good, why should I after what you did in 6.0?
6. Conquest changes, well for me at this point it can only get worse. Its OK at least for me as it is now, for the first time in conquest history. As such any change is not going to be a good one.
As for SWTOR on Steam. Well ok for players that want that. I did have a stream account but not used in years. Don't even remember my account details. So the only question here is, going forward is this going to be a must-play via stream account, or is it always going to be optional?
