On July 11, Star Wars: The Old Republic players will be taking on Esne and Ivela in the new Sisters of Carnage operation. The new operation is just one of the new things arriving in Update 5.3. Also included in the update is a new Umbra flashpoint, class changes, and more.
On another note, the BioWare team is looking for player input on ship balance, itemization, and friction points. Those looking to participate in the discussion can do so on the SWTOR forums.
