In my opinion the event is far too long and after the first few days becomes extremely boring. Quests for the event lack any real thought (Train 'x' amount of times, Reach 'x' rank). Perhaps the event shop should refresh after a time period (weekly?) to allow the player to have a wider choice of items.
Nice artwork though, although i'm not sure why in the Ranged event the king is sitting head-on from the archer.. i'm surprised his wooden platform is strong enough to hold up the weight of his balls.
