Forget about the additional "Players". What gets me the most, here, is the sociological aspects of the worldbuilding.
I mean, I understand it's a game, but really. When you have the top-rated school in the nation basically being an incubator for ass holes to make them into even bigger ass holes - and worse, ass holes with actual, temporal power, then it means that the rest of their society is that way as well.
But I haven't seen any signs of it, and the MC hasn't made any comments about it.
Keep in mind, here, that this is the best school in their nation. And the people who graduate at the top of the class from this place supposedly go on to even bigger things. So even if this is the only school where this kind of thing is tolerated, it's still where the people who can decide the direction of society go to for their education. It's not a small thing.
