Who it's for, and whether it holds up.
The title is doing real work here: there's genuine comedic promise in an assassin class that refuses to play by its own rules. The setup is solid enough. A reborn protagonist with foreknowledge of an apocalyptic game jumps back to launch day and builds his character in a deliberately perverse way, stacking long-range skills on a class designed for close-quarters kills. The early chapters have some fun with the concept, and watching him exploit game mechanics to make a theoretically broken build actually function is satisfying in the way these progression stories can be.
The problem is that the fun doesn't last long. The power scaling accelerates so fast that challenge evaporates almost before the story gets going. A level-twenty-something character one-shotting a level-75 dragon isn't a payoff, it's a story eating itself. Once the MC becomes untouchable, the encounters lose any weight, and you're left watching numbers go up without anything at stake.
The balance between the game world and the real world is another weak point. The premise hints at a merging of realities, but the story never seriously engages with that. Everything stays firmly in-game, which makes the real-world stakes feel more like set dressing than a genuine thread.
At a 3.3, this is a story that finds its premise more interesting than its execution. If an overpowered protagonist doing absurd things to a game's class system is the whole appeal for you, there's some mileage here. But don't expect the challenge or the clever strategy to hold up past the early chapters.
