There's this mindset that has been created by the usage of afk drilling and it's that people believe that they can reap the full benefits of an event without even having to play the game. Is this what most people want? If so, oh well.
This isn't just limited to events; the exact same thing is happening in the Tapasco mines. Isn't it a problem when a guaranteed money making method is available for people who don't even want to play the game? The Lv up rewards on the website were removed due to "abuse" but I never see the same treatment applied to events that focus on drilling. At least people are playing the game to earn Lv up rewards.
Speaking of events, there is one past event that I would like to mention.
At the time that I joined this server, there was a board game event going on. I loved this event because it gave you the option of monster hunting or drilling to obtain giftboxes. You had to collect six pieces of a die from opening the Dice Star Giftboxes in order to complete a full die. Upon completion of a full die, you are allowed to make a dice roll on the board game. All tiles on the board game had a Carved Wooden Box. The great thing about this event was that there was a huge variety of items in these boxes, some of them being exclusive 4G items. I was still a new player at the time so it was thrilling to open all those Carved Wooden Boxes and receive loads of useful equipment.
