While it's true that the login items are very bad this month, we shouldn't single out one or two items just because they can be obtained very easily. Rather, the purpose of this login campaign is to provide all the evolution foods for Monster Rearing to compliment the Monster Rearing campaign. While it's true that the vast majority are very easy to obtain, some things like Burdock might be more annoying to get. And if you are going to include Burdock, you might as well include every item that you might need. It would make much more sense if they were all 100 login points at most but at least it makes sense that every item is included. A few months back, they made all the base weapons for the Oboro weapon quest available via login points including the weapons that could have easily been purchased using Sparks. It's just a matter of being complete and making the whole set of items available instead of just a smaller subset.
But yeah, for the majority of the playerbase, these items are quite useless and probably deserving of derision.
