Comments of chapter undefined of Author Got an SSS Class to Fight His Own MC

Just a thought for you my author, How about changing the term 'Level' with 'Tier'. I know that the difference isn't much but whenever you mentioned a character level in one digit, my subconscious automatically treats them as a mob or weak even if he is an MC who is level 9. Maybe I'm addicted to reading novels where the level is high up to 1000 but still using the word Tier 9 does not sound too bad either.
