Maybe they will remove the guardian mission limit (40 boxes per account instead of a character). They already have a little gold (the economy will not suffer). At least there will be something to do in between the group searches in the dungeon.
Unlikely because the change happened since several people were using bots to farm that on different chars. Especially in Korea so yeah thats usually why we can't have nice things in this game anymore - because the same retards abuse it each time.
