I do agree on the need of new content. And while new ops and flashpoints and warzones are cool, I think the need for the quality of life and sandbox features are greater. Even if I can hardly belive that I wrote just that.
Im thinking about minigames, social options (animated emotes, chat bubbles), a LOT of customisation, not just the character but the ship also. To give players little things they can spend time with when they don't run flashpoints and operations.
