Cristian_Enachi To me, as a writer and a reader for novel that has system, I just think It's just easy to write and make it's easier for us to understand their strength.
In my opinion, it's just easier.
Most readers , even writers don't really want to struggle in creating and understanding why Our MC is like this... Why they are strong, what abilities and hidden abilities they have... You just need to show their status and "poof!!" Everything just make sense by itself.
And that's why it's easier.
Most MC that are too op is just too OP that they have too much abilities even the writers and reader won't even remember and cares to read. Some Readers, including me just skip that part ... Lol.
Still... It's just easier you know...
Like,if the storty doesn't have system, let's say the MC has dragon blood. And from his kind, he has many abilities. And from his abilities, there are more and more little abilities that can be explained but if it was explained, than we will need more than 10 chapters to explain just their abilities.
If there are system, just show us their status in one chapter and the reader will be like.. "huh.. he's strong, choose to read it or not to read it."
