Sir, Dr. Mario IS MARIO. They are not different characters, they are literally the same person. Lucina, Marth and Ike are all extremely unique characters from a franchise that still is not as beloved as it should be. Clearly you have never played ANY fire emblem game in your life so I would appreciate it if you would not insult a franchise I love by calling these characters "lol Marth x 3 if Dr. mario is just Mario with different colors"
I'm not going to argue about the clone stuff because yes, Dr. Mario is a clone of Mario just as Dark Pit is a clone of Pit, Toon Link is a clone of Link and Lucina is a clone of Marth in this game. Dr. Mario, on the other hand, isn't JUST a clone, he is LITERALLY THE SAME PERSON AS MARIO. Would you really be happy with a game that has Mario x3 (Cause Luigi is just Mario recolored like Lucina right? Lol).
I'm sorry I got angry. I just really love fire emblem and don't appreciate you knocking a game you clearly haven't bothered to play.
