I'm one of the ones that quit before the server ended, and i keep in contact with other people that did so too (NONE guild).
I suppose it isn't worth investigating too much into this, because tbh there's plenty of reasons:
- it's summer, people want to chill on the beach, not grind Devil Square
- most mu players are 25/30 +, we need a break from time to time to deal with real life shit
- the old mu server model where people played the same DB for 2-3 years is simply not viable anymore, mostly because of the previous reason. i think OS does a very good job about this, bringing something fresh every 4-6 months.
To all the haters, don't take it the wrong way. NONE will most likely be back, but now it's summer, time to chill
