Some small bugs are being addressed in Patch 5.2.1, such as one that prevented players from (re)gaining Dorne or Quinn as a companion on the planet. But of infinitely more interest is word of better Iokath rewards, such as more command experience and credit explosions, for doing dailies. The studio also added loot in the level 51 to 64 range for veteran and master flashpoints and fixed some niggling issues with the Gods From the Machine operation.
SWTOR fans are going to want to log in starting May 4th. Players will get a free astromech mini-pet through the 8th and enjoy a double XP event through the 14th to celebrate the “May the 4th” unofficial holiday.
