It is so hard to imagine him being 18 that time skip really hurt the story as I can see him being like this if he was younger and didn’t spend so much time here. Slow character growth is fine but I have seen that done well which is rare and having a mc who acts the same as he was when he was 8 after ten years is a problem especially considering his environment he was raised in. I also dislike slow character growth usually as authors like to go with as dumb of an mc as possible with the goal to acting like a rational ***** while they are already grown up. I like it better if the mc starts normal struggles with killing, how to handle situations ect but I am sticking through to see if he does change within a reasonable time frame(though ten years of hardly changing besides his skills seems ridiculous).
lots of negative comments here..and i agree..the EQ level of the MC or even the story is a mess..you need to be more transparent on how you portray the characters thought process since you are currently doing a poor job of convincing your readers. instead of enjoying the story, i am getting fed up with the MCs behavior mainly.
