These threads are pretty ridiculous. Essentially, what I'm getting here is that you're out leveling content too fast. This must mean you're not doing any of the quests for the story/dialogue bits (one of the better/best parts of the game), but for the varied and wonderful "Go here, kill 1/5/20 of these, and pick up 2 of those," quests?
I'll go ahead and respect you're opinion, but now that we've settled this- Why can't you just do the story quests of a planet until you're the right level to move on? You won't be under level then. Ultimately the main problem here is that the vast majority of the playerbase is enjoying double XP, but because a few (albeit, loud) people don't like it, they should end it all? A bit selfish and narrow minded I think.
