I really want to refute the B moves comparison thing. Just because something is inspired/derived from something doesn't make it a clone. Heck, the only ones that can be considered "clone" as far as Wolf's special attacks are concerned is his Down B and FS, and even they have their own properties.
B
With the argument given for B, you might as well say that all projectile moves are clones because they are all projectiles. What makes them different is because of their properties. Wolf is VASTLY DIFFERENT from Fox or Falco. It pushes enemies back and it deals a heck more damage while being SLOW. It has a bayonet that deals double damage when up-close. Heck, the graphical look is different as well.
Up B
You might as well complain that all Up B's are clones because of the fact that it gives vertical recovery to most characters. Wolf's Up B is a lot different, as it carries enemies with him, deals multiple hits, little-to-no charge time, goes farther, and can kill edge-hogging with the last kick freeze. Fire Fox and Fire Bird, as far as I know, don't do that.
Side B
With the argument given, you might as well consider that all dash-based horizontal moves are the same. Wolf goes up in an angle, SPIKES/KNOCKBACKS on his sweetspot (his reappearance from the dash), and works like a recovery move.
Down B
This move is actually more of a DEFLECTOR than a Reflector. It deflects projectiles at a proper angle instead of sending forward, has wider range, and doesn't stop his momentum. This is the more "clone" of all the four, but still stands out.
Landmaster
Yes, this is a cloned move. The only thing that makes it different is that this deals more damage and knockback, has Falco's boost, and has little screen time.
As far as story importance is considered - Wolf has an equal importance as Krystal is. As far as Adventures go, Krystal only played as a damsel in distress, and DIDN'T EVEN USE THE STAFF. Assault made Wolf important, acting like the second James for Fox. In Command, one can argue that they can simply forget Krystal, as there are tons of story paths that actually IGNORE her.
Potential uniqueness? I have a feeling the supposed potential uniqueness is basically a similar move the Star Animals, only with a different animation/graphics.
In any case, let the Wolf hate slide. I dislike it.
Besides, Panther trophy is better.
