This may count close to spoilers with out going into details but prepare to be disappointed in the Big Bad Guy(BBG) lack of cool skills or even menace. For some magical reason out heros unique tier 4 classes come with skills that are better then tier 5 classes. Also once again stats only matter when needed since some how out MC will is so great and unbreakable but how did she beat someone who should also have stat scaling who was 100+ levels above her??
TLDR: You should read to finish the story not because it will be great or epic
