Seems to be as dead as every server except Bera now. I used to be a dedicated windia player but it's so dead I felt rather forced to start playing Bera. Even though I tend to play solo (as making in-game friends is hard) it's still boring to play on totally dead servers.
It's like Nexon's purposely trying to slow down progression even for people who invest money heavily into the game to make things faster for themselves.
That is exactly what they intend.
Once you've hit 250 and maxed all your nodes and symbols, and beat all the bosses (possibly with a squad), what else is there to do on Maple? Some turn to FashionStory, some others just stop playing except for a weekly HLucid run and maybe a bit of flexing in Dojo or Dream Defender.
So yes, Nexon definitely wants to slow progression down, so not that many people would be in this state. They raised the cap on symbols, and may well do so again, but they don't want to power-creep too fast with more caps being raised, so they make it harder to reach the existing caps.
