I've played this damn game off and on for over a decade, and it still has the exact same problems.
Nexon forces all kinds of new content down everybody's throats, yet doesn't bother to focus on major issues, like oh I don't know, server stability.
Every single update has hours of unplanned maintenance, and then they give us "compensation" by adding a few 3 hour blocks of 2x experience, which nobody can enjoy because the game lags too much to do anything.
The burning event is pretty much almost half way over, and the game is still unplayable. It takes 3+ seconds for any keystroke to register.
It's sad when private servers have similar player populations, and better server stability.
