I am sure this will make a few people happy, mostly those that can't make the friday/saturday runs at 6am server time. They usually run 6 of each at that time, so you may want to be open to increasing the lure count depending on if anyone recommends so. It usually takes about 4 hours total to run that many, depending on planar tear frequency and amount of other people playing around in the Dunes of Akala region (where we usually run them).
Of course, we typically don't blast through them since we bring out some low-level characters and go with slow dps and no aoe to make sure they get some materials as well. But, it is all up to you in whether you would take along people lower than about 45 and your rules regarding damage output.
But, if you already knew about the Friday/Saturday crifting outtings and how they were run, then ignore most of this post. And you can completely ignore it anyway, and run your Sunday criftings however you want to :). Anyway, I hope you get a nice turnout. Don't forget to include members of the other faction as well :)
