Ahhhh.....
Mmkay, I'm gonna give this one last go.
I'm gonna break this down into parts.
Whatever dude, it's a significant weapon and it's a canon ability of his. There's nothing saying he can't have a moveset adapted in Smash where he uses both swords and axes, especially considering all the creative freedom Sakurai takes in Smash. If I were a dev, it'd be a logical move to make, I don't see any arguments against Ike using axes that hold any ground. Hell, I don't even know why you are arguing this...
Chrom is a rehash of Ike because his design is based off of Ike. Even his personality takes some inspiration form Ike, the proof is int he pudding CHROM LEARNS AND CAN USE AETHER, and ability that was originally exclusive to ONLY Ike. It's one of Chrom's signature moves. So you're telling me, that having TWO characters in Smash who use the same recovery move is "fresh and unique?"
Also, Lucina is a rehash of Marth and you know it, quit spouting stupid **** to derail the topic. Both of the heroes of FEA were based off of the two most popular and iconic lords in the series, Marth and Ike. It's a simple marketing strategy that has been done in Japanese media for ages, it's nothing new. You see this kinda pattern bull**** in anime and manga all the time. Copying off of previous successes sells well because the sheeple will eat what's popular before they eat what's good. It's why ****ing Nurutu is so goddamn popular. And before we get off topic, Western media is guilty of this too, it's just Japanese media is more subtle about it and thus is more commonly seen there.
The word you're looking for is "subjective," and no it's not.
Take a look at this thread over here:

Ok, now please tell me, where exactly would you put Chrom? And what exactly can you do to make him stand out from the rest of the sword users. Yes, Chrom is not only competing with Ike, Marth, Roy and Lyn. He also has to stand out from Link, his clone, Shulk, Isaac, Takamaru and all other sword users that we could potentially have in Smash. Smash isn't there to represent all series equally or evenly. It is a fighting game where all competitors have to stand on equal ground in regard to gameplay. So in this light, Chrom has to be seen as an appealing candidate that can do something unique that no one else can to be seen as interesting.
In addition, his implementation has to be simple and logical. I've seen the 'pair up' mechanic come and go as an excuse for the FE:A lords, but lets be real here. That isn't natural, it's forced as ****. People are grasping at straws at that. The best way you could make it work is as a sort of tag-team mechanic, but here's the deal. Why should the FE characters get that over Diddy and Dixie where it makes a HELL of a lot more sense to have it, or why them over Zelda+Impa? That's why it's forced, it's looking for a way out to make the characters stand out from the rest. And that's not even looking at the programming complications of putting a duo character like that in the game. We already heard how Smash 4 3DS has problems with the AI on duo characters, meaning we might not see Melee vets the Ice Climbers because of it, and this is your proposed solution? So the only way out is a transforming character like Zelda, but once again, we already have that mechanic/character in the game. Why add another? How is that different, unique or fresh? Not to mention Zelda already suffers from balancing issues due to the lack of synergy between her transformations. On top of that, it means adding TWO FE characters with a forced gimmick that might not work, when if we got two FE characters Lyn and Roy together would make just about everyone happy adding a character that can do what Chrom can already do in regard to playstyle, but much better, and a speedy swordmaster that is TOTALLY fresh and new in regard to playstyle. Smash has yet to see as super-quick battousai sword user similar to Kenshin, and many have been wanting one for a while now.
tl;dr, Chrom is boring, period, and the Duo mechanic is forced and lame. Disagree, then once again, I invite you to write up a moveset for him to make me eat my words. If you can make a moveset for Chrom that is more appealing that my Lyn or Ashley movesets then I will eat my words, praise you, and support Chrom.
The best I ever came up with was by outstretching what Holy Shield can do, and making it into a sort of stat boosting move and the central focus of his fighting style, but guess what, we ALREADY have a clone character that can do that canonically and could really benefit from it as seen in his incarnation in Project M (Lucas). So once again, why Chrom over him?
Then you and I are gonna disagree in just about everything, and that attitude is probably why you and I will likely butt heads and come to blows until I grow bored of arguing with you. I don't care if you like them or not, you should at least try them. Saying "I refuse to play X because I don't like that genre" is like saying "I refuse to listen to Nujabes because I dislike Rap." It is a very closed minded and (rather) annoying attitude, and you miss out on experiencing some really amazing and beautiful stuff. Word of advice, drop that and learn to be more open-minded, not only will you expand your vision and horizons, but it will make you a more likable person. Just friendly advice is all. After all, we only live once, so you should at least give yourself the opportunity to try everything once, otherwise you're not really living, just existing.
