This is in response to most of the blatant anti-Chrom comments, but I'll just answer it by quoting John.
In my opinion, Chrom can actually become one of the more unique characters to ever be in Smash. Now, before you call me crazy, let me explain.
Chrom actually has everything he needs to be the series' first true stance-switching character. I'm not talking the everyday transformations that have graced Smash so far, but instead a true stance-switch accessing new moves via a button input. In Fire Emblem Awakening, Chrom promotes to Great Lord, in which he has access to the Falchion sword, as well as lances.
Now, Fire Emblem is a strategy series, and as such, often involves choosing the right weapons to get the job done. This really isn't shown in Smash yet, and this is where Chrom comes in. Basically, his sword stance focuses on durability. In his Sword stance, his weight is increased a bit due to it being a heavier weapon. The sword style itself is basically the lunging attacks shown with some of his sword moves in Awakening. Additionally, Chrom's Falchion in Awakening has an added healing bonus. When using Sol (my current version of his Up Special), Chrom heals a bit if it connects. However, with the Falchion, he heals a bit more than he normally would. However, this stance lacks reach.
That's where the stance change comes in. With the press of Down B, Chrom sheaths Falchion and pulls out a lance (in this case, the Spear from Awakening). With this, Chrom switches his focus to reach. The Spear can reach a lot farther, and Chrom is lighter on his feet. However, he can't heal as much. Additionally, his Side B (Luna, in my case) becomes a projectile attack by him lobbing his spear.
For added kicks and tricks, the switch between weapons would be effortless and mostly lagless. This could allow for some interesting set-ups, and you'll always keep your opponent guessing.
Just my take on how Chrom can be done well.
