I feel like if Marth, Roy, Lucina and Chrom didn't share 90% of their moveset, the FE additions wouldn't be so divisive. I was thinking to myself "Why do I dislike FE characters? I'm happy for their fans, but I never like seeing more FE characters..." and I really think it's because 4 out of the 7 characters are essentially "clones" with slightly different appearances. Fox is 100% clones/semi clones, but it doesn't receive as much hate. I think maybe that's because the characters look completely different (and there are only 3 total). Mario only has 2/7 as "clones" (Or did at the beginning, Mario and Luigi are much more different now), Zelda has 3 slightly different versions of the same character but doesn't receive as much hate. It's interesting.
