i thought rogues were useless

Modern Society changed 82 years ago when the entire world received the same message. [Welcome to the League!] [Since your world is so underdeveloped, you will be given a grace period of 100 years.] [To help your species grow, Dungeons will be available to conquer, along with Gates.] [Good luck!] After that monsters appeared all over the world and more than half the population was wiped out before Human's began to learn to defend themselves. Modern weapons were useless, but Humanity discovered something far more potent. The system. Everyone on Earth received a status screen, much like a game, that rewarded them with insane growth when they killed monsters in dungeons or gates. Through the past 82 years, society changed into one that abided by the law of the jungle again. Only the strongest survive, which also gave birth to preconceived notions of what classes given by the system were strong. If you got a weak class from the system, you were condemned to a life of struggle, and the conceived weakest class was the Rogue. There were almost no Rogues who were able to fight any other class the same level as them, since the class was only useful as a scout, or to spy on your enemies. Yes, while Humans had developed and grown stronger, they grew more divided. Causing people from Guilds to be at odds with other Guilds, forgetting that the original purpose was to grow stronger as a collective for what was to come after 100 years. What came after 100 years was that we were now in a dimensional tournament to bid for our survival. Failure to win meant that your dimension was wiped clean, to be grown from scratch to try again billions of years later. All for the enjoyment of various Gods. Follow Xeon as he discovers that the Rogue class he has been relentlessly bullied for having, has more potential than the world previously thought.
