Review Detail of Renruter in Earthland's Gamer

The main character is a murder hobo. If someone looks at him bad, he tries to kill that person. Its also full of plot armor. The main character needs this extra rare thing in order to progress his current class. And almost within 1 ( time skipped) month of him figuring that out, it gets handed to him on a silver platter. There is no supporting cast. There are no side characters. Only extremely clicheed cardboard cutouts. The muscle head, the arrogant young master ( theres been a lot of these). The world doesn't really make sense. Theres this amazing god slayer magic, but its power fluctuates wildly depending what the plot needs. Sometimes its known to slay gods, sometimes its not enough to break some random flunky shield.
