while HW Dorf would make a great DLC outfit, i really don't want a dual sword Ganondorf UNLESS is explicity Wind Waker Dorf, or Pig Ganon, and as for pig ganondorf i prefer way more the trident.
I'm neither a fan of Sword Dorf either, as another user posted, for me the perfect dorf moveset would be keeping his brutal them while adding some more magic. Still, even if he isn't much canondorf, actually Falcondorf is really fun to play as, as Sm4ash falcondorf is probably the best falcondorf to date (not the highest tier one though). Still I would love if they at least do a small overhaul to falcondorf, specially replacing his more "athletic" and "Flexible" moves with more magic inspired based animations.
A good example would be his vulcano kick, I actually like the move and the concept behind it, but i don't like at all the animation... I wouldn't mind keeping his framedata and hitboxes, but changing the animations from him to charging energy n his hand and hitting the floor, or stomping the floor sending a magic wave to the point of the explosion. his kicks from down smash could also be replaced by magic explosions while keeping the framedata and hitboxes. stuff like that.
Still i would make warlock stab his new non custom B. but still would rework his animation, i mean the move is cool and all, but the animation is the strangest sword attack ever. I would play with the fact that the sword he uses isn't his sword, but the sword the sages used to seal him (and since his model even have the stab wound) to do something more brutal, and make him materialize the sword in his chest, taking it from there (instead his magical pocket) and then proceeding to Stab (and i mean a real stab animation) The attack have so much startup that he would probably still be able to pull all that off while keeping mostly the framedata (maybe his range can get a little buff though).
All of this changes would keep the core of falcondorf almost intact, while giving him a lot of canondorf flavor (changing his roll to a pseudo teleport would also help)
with all that said though, this brawls mods are things of pure beauty (and dark magic).
