Rannsu why was DOA4 bad when it came to buffing or nerfing. Some characters might have better moves than others but at the end of the day in DOA it matters if youre smarter than the opponent, not which character ur using. People said Leon was low tier and that he was shit but I swear to god I could beat anyone in this universe using him and they can use any high character from here to YA YA land.
A guess: you play mostly online? Not that many of us have a choice, but still...
Not knowing frames is not knowing the game, period. You're crippling yourself. They aren't the whole story but it's almost as bad as saying that "I don't need to know which attacks are high or mid or which attacks stun." I'm not trying to rip but in this kind of game this is a ticket to scrub world. You need to know these things.
