Ok you can kick me in the head if you want to, but this is another quest that is repeatable and is super easy.
The Cursed Crystal quest. Go down to the bar on Mustafar and talk to like the only human on the left side as you enter and get the quest.
There are two way points you need to go to. I don't remember them right now, I can post them here in a min. But all you do is go toward the crystal flatlands (I think that's the first area) and then you head to the burning lands, close to the mining ruins. Hang out there for 5 mins, and you will get the XP for the quest. 100k and as it's the last day of XPx2 you would get 200k XP once you get the 2nd message after sitting there for 5 mins. DROP THE QUEST! I repeat DROP THE QUEST! If you start heading back, you will complete the quest on accident and not be able to repeat it, I would say it take around 1/2 hour per loop. But it depends on your level when you start. I can get the WPs for the quest if you want them. I didn't see anything on this site about this quest for XP, so I thought I would post it. But this might just be another common knowledge thing. *shrug*
