The 1.4 patch is up and running in the Star Wars: The Old Republic test server today. With the new Operation, Terror from Beyond, also comes a shipload of updates for all of the classes. Outside of some basic combat animation tweaks, there have also been some major changes with the addition of new skills and/or reductions or increases in several cooldown timers.
Some notably changes have been specifically made in regards to the speed boost skills of the Jedi Consular and Sith Inquisitor, an improvement to stealth mechanics and making sure that all classes have at least one interrupt skill. Companions also have the ‘match color to chest’ and ‘hide helmet’ options that were mention before as being in development on the forums over the summer. You can find all of the information about testing the new patch and full patch notes on the official SWTOR website here.
