The LTQs had units in them that gave -20% health regen. One had 2 of these units. DBJ was one of them.
LtQ had a serries of missions with random rewards. Mission was attack 1 barracks then 2 pvp wins then a map mission.
Other games repeat LTQs and the prizes to give new players a chance at them. Since we have brought back the LTBs to help players that missed them why not the old LTQs also?
It was possibly the best (non faction)event gree has done. New players ( under 18 months or so) would love it and the rewards.
