I posted my question from last week too late. As a result, it didn't receive an answer. My question remains, so I'm just going to quote myself:
Right now, there are two types of Shadow Equipment:
1. Event Shadow Equipment dropped during the event by event monsters
2. Shadow Equipment sold by the Cash Shop
Last Tiki Tuesday, there was some discussion about the potential value of event Shadow Equipment, and I just wanted to reiterate that point because I didn't see a response in the thread itself. +4 to all stats may not seem like much, but it is very useful in certain situations like brewing. The complete set basically offers 4 stats you can't obtain anywhere else, even if you purchase the Cash Shop Shadow Equipment. These stats are also provided without taking up any of your normal equipment slots, making it impossible to find any substitutes.
Other items that are obtainable only from events do make their way back into the game periodically. Examples include Adventurer's Trusty Towel and King Poring Hat. Other items such as the RWC Rally Box can only be obtained from the Cash Shop at certain times of the year, but even such items eventually return.
At the moment, there's absolutely no way for newer players to obtain the 4 stats from event Shadow Equipment. Aside from being unfair to new players and older players who simply missed the event, taking a functionally useful item out of the game permanently seems contrary to precedents set by previous events and the Cash Shop.
I suggest making event Shadow items tradable and allowing the event to return.
Campitor mentioned the possibility of placing the Shadow Equipment event monsters on "that map you go to tame the little poring on." If he means the pet taming map inside Izlude's novice academy, I don't think it will work very well because there's no way you can get back inside after you graduate. The monsters should be on a map any class (not just novices) can get to.
