Oh boy, here we go:
1. No idea on Korean law on gaming, but the only way to "farm" for an event would be to make the event token available as an unlimited item that can be obtained through repetitive gameplay. This has never been the case since event tokens were always limited so not sure how that particular law is relevant here.
2. The lamps had three tiers all with different rewards with the higher tiers requiring gameplay to obtain another item (cloth) in order to transmute said higher tier lamps. If NCSoft wanted people to actually "play the event," they could have also made the lamps only obtainable through gameplay.
3. Agreed that the last event left much to desire and definitely should look towards the future instead, but how will the devs create better events if they do not learn what went wrong in the old ones? Make a stand. Tell NCSoft what they messed up on and hope they do better.
4. Events (and games!) should be fun. Not a chore. Rather than set an alarm every 5h, shouldn't a game focus more on GAMEplay and not, "Hey, come on every 5h to open a lamp!" (Moreover, the first thing I do when I come home is change, prep dinner, etc. and surprise, not turn on my computer just to open a lamp... but you do you.)
5. This is actually the first expired item from the past three years or so that become "unusable" while other expired items in the past were still able to open, process, use, etc., but were no longer used / redeemable anywhere else in the game. For veteran players, no idea how we would not be bamboozled by this.
6. This is also the first event in three years that utilize this strange CD function. Most likely, some of you are mistaking the "jackpot" pouches that was less of an event item and more of a gift that provided awesome things every 10h with a max opening of 10 stages. In other words, 10h CD / max 10 openings over a month timeline VS. 5h CD / max 60 openings over a month.
7. Don't get me wrong; I never expected to open all 60 of the lamps either. I was perfectly fine with opening as many as I could within the event + redemption timeline (usually 2 months), but then half of that expected time disappeared with no warning.
In the end, as mentioned before, this event was poorly designed (and should be shared as such with the devs if only they would listen), but the biggest issue is the lack of information on the lamps' expiration. The tooltip, announcements, etc. etc., nothing stated the lamps would become unusable except for the newest patch notes posted on Tues morning, about 17h before the maintenance.
