It's called main character's idiocy syndrome.
There are also examples of other diseases such as:
- MC's lolita complex.
- MC's big tities attachment philia.
- MC's cheating and harem addiction.
I was looking for someone to say this because this was exactly what I had thought. It's one thing to grind before the tournament starts, but it's a whole other thing to be leaving it at like 99.9%. That's way too risky. It would have been more realistic to be at 80%+ and just grind the rest later.
In hindsight, it was probably written this way to be funny, but it's not really funny. It's just dumb lol
I know right?! An experienced gamer like him would never do that! (╯°Д °)╯╧╧ But I guess the author really wanted to use it for the plot?
if im gonna be honest leaving your exp points at 99.9% when you have special event coming up is pretty stupid, like why can't you leave it at 80/90% why max it when you never know when you will get exp accidentally..
im sorry i just feel frustrated..
