Can't ever find enough people to do a party quest, not to mention parties are worthless since creatures are to simple to kill. My suggestion is mix all game titles so that the remaining players can have fun playing together before the match completely dies. An additional bonus EXP/Drop per party member feature in the celebration tab(to remove solo coaching cheapest Maplestory Mesos and bossing).
A massive majority of people are stopping this game. I truly strongly feel that the merging of ALL game servers(excluding reboot) will help players reunite because there would no longer be separate worlds. You know better than I do, that would possibly flooding some of those high-end training areas of the sport, so an additional 10 channels could be inserted to fix this.
Reinstall the removed feature "Auction" out buy Maplestory 2 Mesos of KMS patches. This removes the requirement for players to purchase free market shops that lowers profit for your organization, but in turn raises appeal amongst gamers(which can cause some players to return which increases overall bought karma koin).
