Perhaps I just never figured out how to grind properly because given time, yes, you will just be able to overpower anything in your way. But I shouldn’t have to grind levels so much that I can sidestep entire mechanics, a game shouldn’t block important, mandatory campaign moments with features so heavily grounded in randomness. It wouldn’t be so bad if the random elements were fun, but they’re not; they’re just frustrating time-sinks. And that’s what most of Mugen Souls is: a frustrating time-sink."
