Well, as for my observation, the events are too boring, they are recycled events. Don't misunderstand, I really appreciate the efforts of the staffs for organizing the daily events we had but I think its just too boring.
By the way, these are my suggestions:
1.) Items obtained in quest ; instead of loot event, make a surprise event that will require a player to bring an item that can only be obtained in quest, the first one who will trade the gm wins
2.) Problem solving ; should be posted in forum, i think math, physics, accountancy, algebra, trigonometry or even calculus can make for a great event, post the question on forum and whoever answers first will win
