Lack of content?
A: ...Well, if you have THAT much time to reach end game and say: I want more content!... then omg do something in real life, or set a goal (get all swords w/e)
Too easy?
A: Run FSC in proto gear. Better yet, proto weapons. Or try an all piercing weapons Royal Jelly/even Ice Queen, if you can afford it. Try to do FSC without a shield... so many ways to challenge yourself
Annoyed because of polaris?
A: Kick that player, ignore that player, report that player, go solo
end game
It doesn't even exist.
Too easy?
Artificially making the game more difficult for yourself doesn't fix the general impression most people get when playing the game with tier appropriate gear.
Your last point isn't even a response to your thread title, you're just fishing for responses there.
tl;dr?
trolololol
