I think if you want something sooner, maybe suggest it in the patch notes? Also, gacha items are probably being reserved for the actual gacha towns as well as event prizes. Proper quote from Aran about myshop boxes:
You guys could open a new thread called new content for CWB, and put up suggestions in it for inclusion when we update CWB, say, maybe in August (our 2nd anniversary). Item must have ggftw link, and not from myshop boxes (if from myshop boxes, the item will come out as form/model only, no stat).
So I have another suggestion; As CWBs are kind of the only proper galder sink in the game, can we add Aria exchange items to them? Items like the card hunter crests, or even the card hunter crest boxes, weird boxes, or the arcana cards and mystery cards. For the items like the crests and cards, maybe have them pop out in decent stacks (5, 10?). Since the CWBs are a gamble themselves, I don't think it'd ruin the game (probably, if anything it might give value to galder once again?)
What do you guys think?
