Just go down to the Webweaver Path with a Group of 5 Members or so. (Maybe an Master Defender to tank)
At the first Spawnpoint of the Wookies ( 15 Wookies or so) go to the Bridge right form you an wait for the spawn.
During Double XP each Wookies gave me 12k XP-Points and to Jedis something like 2,2k.
They spawn very short, less than 5 minutes.
You can use some kind of AFK-Macro if you are sure the others are taking the damage and not you.
/ui action cycleTargetOutward;
/ui action toolbarSlot00;
replace the "00" with the Number of your F-Key for the attack starting at 00 e.g. 00 = F1, 01 = F2 .....
