Review Detail of Fullpower in Fate/DC Universe

Even though the start of the story was a little cliché and felt a little bit rushed, the last chapters have developed the MC much more; one of the weaknesses this novel had. However, characters other than the MC still feel bland due to poor descriptions of their mannerisms, emotions and reasoning. The novel would be better if the hard work that the MC would be emphasized more. After all, right now it feels like power comes too easily for him. The system is basically a Deus ex machina that gets him out of any problem without consequences. I would really appreciate it if less powerful servants appear and the MC has to improvise or show his creativity with them. Moreover, I think he should be allowed to fail. All his missions end up with little to no consequences; even his first mission, where he was really inexperienced.It would also help if you could add a little introduction to the servant's abilities. For example, after so many chapters we still don't have a description of the ability that he gained from Merlin.
