she's still marth-lite and that's better than chrome could ever hope to bechrom is still super fast and super strong and has a big sword. that will take him places... BUT as players get better that shitty recovery is going to get exploited.
then again you could say the same about captain falcon in melee and that hasn't stopped people from performing extremely well with him. chrom has some really great tools. I was surprised still to see lucina in esam's top 10 over chrom. i'm not convinced that she's better than chrom yet.
chrome is essentially little mac with a sword and (arguably) an even worse recovery - one that doesn't even have i-frames like lucina or the horizontal capability of mac's.
