In light of multiple days where the game was completely or largely unplayable during the event period I recommend an extension of the event by one week.
Such issues as frequent disconnections, maintenance, lag spikes, etc have made it more difficult for people to level up and complete the main story quest, get their 200k MGP, and get their mount from the event. With many people recently joining, these issue may have made it impossible for them to complete the event so far.
