I'll touch on my reasons about the Hadouken last. But first, could you be more specific about the stairs? Do you mean ladders? Which ones? I agree about the dogs, they do freeze up. I have noticed the ladder in Primate stage in the Ride Armor section. I'm mixed on whether you should be able to fall through or not, because that offers a quick way up and down. Now, for the Hadouken. I get wanting to make it easier, but there's the balance of what's too easy for a move that one-shots enemies and most bosses. I largely see it as a move that needs and should be practiced, one that separates the good players from the best. I for one don't find it that difficult to execute, and same with many others, although I recognize that are many that do have problems. My biggest issue with having it as a mappable feature in controls is that it ruins the secretive nature of it being a collectible upgrade in the game. If I was playing it for the first time, I would rather not be spoiled by the menu options telling me about a Hadouken input, because that would ruin the surprise. Most MMX fans should expect to look for a special upgrade after getting 100%, but it's nice on the first playthrough to have it be unknown. My second point is that mapping it to a defined place on the controls limits the other inputs already laid in-place. For instance, the special moves, weapon select, dash, etc. I have for my dash on L1 and Special move on R2. That's just my preference, but it works for me. Finally, I feel like altering undermines the hard work and practice many people, myself included as a mostly casual player, have put in on the Hadouken and Shoryuken from the original titles. It feels like a cut to all my practice I put in to be more skilled. But, I have no resentment towards your reasons. I hope you can understand the other side of the community that prefers the traditional way. At any rate, there is a vote on the Discord, so you can put your vote there. There are not many votes in so far, but the vote is favoring to keep it as is.
