It was (mostly) a joke. I'm not salty about the little dog-and-duck pair, I just find their playstyle anti-fun, which feels out of place given Sakurai's design philosophy. No fun to play as, no fun to play against (and not even in the DLC way where newer/less experienced players get bodied and have to accept it, making it an EZ win button around casual players and an uphill challenge worth taking for more competitive players), just an underwhelming addition to the roster that I don't believe anyone asked for. Might just be a personal thing, not entirely sure.
As for Fire Emblem, the only reason it exists in the West is Smash, so it makes sense that the tactical series would get heavy representation as a kind of thank you note. I'm just trying to cut out the redundant "language", as it were.
if you seriously think duck hunt is anti-fun, then I wonder how you feel about Bayonetta dealing 70%+ from one hit or Cloud always both being unapproachable and forcing you to approach. Obviously Bayonetta is sick af, but still has a playstyle that alienates a lot of what Smash Bros is about, especially in the fourth installment. In fact, Duck Hunt is one of the most appropriate characters for Smash 4, a game in which defensive options are extremely powerful (rapid shield regeneration, airdodges, rolls, spotdodges, etc).
Nobody asked for Game & Watch or Mii Fighters, and frankly, most people asked for a couple of other characters besides Corrin, so the logic of "what people want" is null and void.
It's okay to have an opinion, but it seems like a very unfounded one based on your incapacity to deflect projectiles or run + shield.
I believe that Duck Hunt is loads of fun to play against because you constantly interact with his projectiles and he has a lot of funny tricks up his sleeve. In fact, the only reason Duck Hunt is considered bad is because he has bad matchups against high-tiers; all things considered, he has the best neutral game in the entire roster, with great aerials and projectiles. Perhaps he's the only defensive character on the roster aside from...Bowser, and maybe Sonic?
Anyway, I've had a few games against a Duck Hunt main, and it pretty much comes down to just knowing how to play and deflect projectiles, etc.
That's weird though. You could complain about Bayonetta combos, Cloud's above-average stats in everything (including recovery, while he has limit), Rosalina & Luma's early kill options and amazing frame data, Mario's down throw up tilt combos, Corrin or Marth's spacing, Ryu's anti-meta playstyle, Link/Toon Link's obnoxious playerbase....but Duck Hunt.
Anyway don't joke about removing a character without any explanation for why it's unfun other than "i dun like it."
Also apparently HAL Laboratory being in the copyright bit has been a thing for every game, which I find odd considering they had no involvement with 4. So that part doesn't necessarily mean anything, we still don't know who's developed this one, though if Sakurai is involved I'm assuming Sora Ltd. is as well.
The lack of copyright displayed for 3rd parties has been used as evidence for this title being new rather than merely a port. I also wonder if there will be even more additions to the roster for this reason.
I also hope I don't have to spend more money on the DLC than the game itself
On the topic of Arms, we already have another heavily range-based character in Inkling (presumably), so adding an Arms character would likely shift the meta into one more about range and spacing than before. For this reason, shields need to be given serious consideration.
