I have to say this is awesome for working lock mastery.
It was awesome to blow through 48 points on my current rank after only turning in 3 tasks. I now have, I think, 22 points to get to rank 9. This helps the slow going of minimal points for tasks that can take a long, long time (especially the one task I had to a few days ago; I had to do 5 reps with a Master and was rewarded 1 measly point...1 point....seriously?)
Too bad the double points only happens once a week. I'll take it, but I just wish the time frame was all day and not just a 6-7 hour window. I can't usually find time to be on most nights. I just happened to get some extra free time last night.
