Review Detail of Mzeeddz in Demon's Virtue

So... I really like the first 200 chapters but the quality of this story gets worse and worse after a while... Id say that it made all the 4 worse mistakes that an adventure novel can commit: 1- Deus ex machina; 2- Fights that last more than they should becase the protagonist waits for the enemy to use his secret technique or to get a power up; 3- Enemies that escape (no1 likes when an enemy escapes, cmon...); 4- All enemies have a second phase, it's never simple... Explanations: 1-Deus ex machina happened when the protagonist died and some random gods decided to revive him and give him a legendary skill because he has potential; 2-Basically all fights during and after the amnesia arc. The fight against the letter S took especially long for how weak the enemy was, Eiro let him power up not once but twice, the waiting was supposed to make life easier for him, but instead he had to use the 'power stone' that the Lady of Winter gave to him and we still don't know if that 'power stone' was a one use only or nah; 3-Crow... Not really much to say, the protagonist thought he was playing with the guy when the reality was the reverse, he didn't use everything he had and the guy escaped after saying something like, hope the next time we meet you'll be stronger, btw **** that; 4-Even in games this shit gets boring... A fight doesn't need to have 15 different phases to be interesting, sometimes an enemy who has a power-up is interesting, but not always. Btw why the **** is Eiro so weak? He has 4 minor arcana cards and is the candidate for one of the major arcana but he still gets stomped by any guy who has only 1 card, like what... I mean, when the demi-lich had the knight of pentacles the guy could predict every attack that wasn't made on instinct, Eiro can't do half of that, he should have incredible perception but he sometimes misses enemies and incredible perception should theoretically increase his reaction time but he still gets rekt, idk kinda weird... I feel like with these 2 cards he should be easily able to deal with some1 that has agility as a main stat...
