I think the 12 hour LTQ was a mistake. It started at 5pm on the East Coast, USA. That means it would end at 5am. In case no one else mentioned it, we are in the middle of a Raid Boss. My guild is on 28/33, kill 30 level 100s. We're kind of busy. If you want to make it fair, do something for 24 hours.
LTQs are very boring of late, and I'm thinking seriously of skipping them altogether. They are just too tedious.
It would have been a little better if the 10% energy regen bonus worked.
