Is there a reason why we could not open up more channels on the server we have? New servers would likely split the community and make meeting new people from the forum in game much more tedious. Oh you are new? Which server do you play? Y? Oh that's too bad, I play in X. I could've given you some of my gear on X.
Because the channels were increased recently with regards to the increase of DAU (yes, including mules). There's a pattern where 2 new channels are opened for every 2x the increase in population. As seen in Channel 8 - 10 being opened when 500 players were active, and 10-12 when it reaches 1000. So let's wish for more players (2000 maybe?) so more channels can be potentially opened.
