Moonbridge is available at level 245 if you've completed the Esfera storyline.
Labyrinth is available at level 250 if you've completed Moonbridge.
And Limina is available at level 255 if … (more)you've completed Labyrinth.
The story is still present, including the final battle. However the battle will be significantly more difficult and you won't possess the Alliance and Goddess Skills to help you.
Nexon cannot help you if you are using 3rd-party software; I highly doubt you'll outright get a ban, but Nexon has stated in the past that you should not run these programs. At the very … (more)least, a lack of support means Nexon cannot help you if you experience issues when using a controller.
Also, the blog you linked is from 2004, and is about running your computer in administrator mode entirely, not about apps that request permissions. You shouldn't run your computer as an admin entirely because it ignores those permission request pop-ups, so you can't pick and choose which program accesses what (at least, you couldn't in 2004, Microsoft has introduced additional security features since then). Running your computer normally produces the pop-ups, allowing you to choose to run the program or not. (less)
As stated, the text is weird, but it appears to be a channel purchase limit.
Also, I believe it resets regularly. I can't tell you when, as I've never hit the limit myself. (less)
The point is that self-sacrifice only makes sense if it solves the problem at hand. You sacrificing yourself to stop the Black Mage wouldn't help people survive, it'd just kill you, … (more)possibly wouldn't even succeed, and leave the rest of the Alliance worse off because now they lack their hero.
A similar issue was lampshaded in the Order of the Stick while discussing Roy's inability to attack the cleric of Hel at the Godsmoot; Roy could attack her, but it'd force the clerics whose gods support the destruction of the world to attack Roy thanks to the Godsmoot's rules. Even though the fate of the world is at stake, Roy doesn't do anything:
Honestly, I've got half a mind to take one for the team and try anyway. Being dead's not so bad. I've got a cool little nightlight with my name on it, and I could go with some home cooking.
But even if I kill her before they toast me, that wouldn't tie this all up with a neat bow.
If I die, my team falls apart and Big X moves into scoring position—and everyone is right back here voting in a week or two.
Recent lesson, connected to that "dying" thing: Noble sacrifices only make sense when they solve the problem at hand.
The only way the world stays saved is if this vote fails and we never have another one
The Durkula arc is eventually wrapped up with a different sacrifice, but this sacrifice makes sense because it actually does solve the problem at hand (also necessary to expand on the plot with the Snarl).
Additionally, it's not so much the "will to survive" as in "eat food, breathe, and don't get stabbed in the gullet by a giant magic sword", it's more like the collective will for the world to survive; the fight against the Black Mage was, at the most basic level, a fight to decide whether or not the world should continue to exist. Someone who escapes a fight just to survive might be a "coward" in some works, but someone who pointlessly stays behind to die when they could pull back and win later would be considered a fool in others.
Think about the similar speech made in One Piece episode 278: Nico Robin turned herself in to protect the Straw Hats from CP9, only for the Straw Hats to turn around and declare war on the World Government; Robin's sacrifice isn't glorious, it's actually rather selfish. In the end, the important part is that her friends fought for her, and nothing is solved by her killing herself, so she declares "I want to live". Because fighting for what you believe in is far more noble an act than simply giving up and dying because of what you believe in.
The trope for this is called Senseless Sacrifice, the downer counterpart to Heroic Sacrifice. You can find more examples of works deconstructing the necessity of sacrifice in the Tropes page, including real world examples as a counter to MLK that you mentioned.
Edit: Also, my character's choices were "I would sacrifice my life if it meant saving everyone else" versus "I must defeat my enemies, even if I have to give my own life to do it". Both were sacrifices. Unless this specific dialog is different per character: (less)
