under the old system the server shut at 1 am they were generally back up between 5am-6am which is 4-5 hours, 3 maintenances = 12-15 hours approximately. New system started with a 12 hour deficit on timer of event plus multiple mini maintenances therefore old system was better. For last two events explorers, quests etc could be launched at 00.00 am, this event it was lunchtime so again old system better, result at least 12 hours of searches lost, maybe more if your southern hemisphere.
