Other events that set high bar previously was Dantes' Prison Tower (London, latest during the time) and Ibaraki's Rashomon (EPU, latest during the time).

Given how both possess high difficulty enemies, I'd say there would be some quests only can be cleared with well-developed Servants which is not weird as by the event we got two Extra Classes with each of their advantages while multiple layer HP bar managed to ensure you'll have hard time to be carried.
