If GMS is so empty wouldn't it be a good idea to lift the IP ban to other regions? I live in a region banned from GMS and from my experience most people I do party quest with are from regions banned from GMS. Problem is we need to use proxys and other stuff to be able to play, which gives us little lag. In my opinion it is OK but many people are really troubled by this and some doesn't even play the game anymore because of the lag. Maplestory was good in the past because there was a big community, there was always people available to play with and chat. I think if nexon opened GMS to more regions, more players would be back, more NX would be bought. Also, I am sure many north american players would come back to the game if the game got more lively.
I mean, we know nexon bans the IP so nexon can sell maplestory2 mesos the game rights to companies natives to those regions, but again, from my experience, Maplestory in my country (Brazil) failed miserably simply because there weren't many players around. People won't buy cash unless they think the game is going to continue in the future.
Also, one of the most important thing in a game in my opinion is stability. I like to know that everyday I can wake up and play the game without gigantic surprises because of a stupid company. I'm sure many people think like me. Having IP ban in GMS, even in 2015, is a pretty big indicator that nexon wants to kill the game permanently.
