Wheter the trope is common or not is obviously related to it's quality. Overused tropes have a lot of chance to be badly done, since they are being used more often.
To me, whether it was time travel or transmigration, it was bad anyway. We just see a different problem xD
I understand your frustration, I just personaly stopped worrying about these errors, since the comic doesn't deserve much energy from me considering its quality anyway.
Mc uses his knowledge from the future later on, so this setting gets a little justification, but that's it. The way it was introduced to us is still very bad.
