Where did they even get the information for classes?! Well, since we know that there were previous "players" before the MC, and the mother of that baby was 3 months pregnant when she was "chosen",means they're settling in the 3rd program for more or less than six months or maybe even a year. So, in that span of time, they could've witnessed tons of abilities and classed them personally. Also, now we know that someone can have the same ability, but the restrictions are different. But idk, I may just be exaggerating but, somehow it still feels shady to me. And also because of the foreshadowing from the earlier chapter. Looks like he's been tricked or made a miscalculation.
