It's funny, I feel they actually made Wario more faithful to how he operated in his own games, while not butchering his Brawl moveset.
It's not about being faithful to your origin, it's about designing a moveset that works and operates well. That should be the first priority, and it's something I took from all the fighting games I played. (I'm a boxer, for example, but I completely understand why Dudley and Balrog in Street Fighter don't exactly embody what makes boxing, boxing.)Project M team is so fixated in making characters faithful to their origins that it makes everything really incohesive, hugely gimmicky and unpolished.
Brawl Wario was about aerial maneuvering and having diverse tools with a lot of options for any situations. One of his best moves that allowed him to do that were his down air and the bike. The bike gave Wario tremendous defense options as it can be used as a recover, to play keepaway, to get away or to even use a shield. What did they replace that with? A very unsafe ranged fsmash. His down air was his best normal, because it made him apply pressure like no other and made him control the pace of battle. They changed that to a completly vertical dive kick that is very situation. The only improvement was the d-smash...except for the fact the new d-smash is nothing special at all. Wario is awful in Project M, they completely butchered him.
You can make a Wario Land-moveset for Wario. You can make the Shoulder Bash work. What the Project M team don't understand is that the worst thing you can do is trying to make the shoulder bash work exactly like it does in the Wario Land games. I play WL games regularly, and the Shoulder Bash is used to clear obstacles and to completely beat random enemies in a platformer,
but that doesn't work in a fighting game.
I stopped playing when they gave Snake a tranquilizer and made Ice Climbers slippery. Even as an MGS fan I really didn't like his changes. At all. They made a once camping character into pure rushdown. It's bullcrap. The only characters I even use are characters that are basically exactly like their Melee counterparts. (Captain Falcon, Mario and Falco.)
It's like making say, Balrog in Street Fighter be able to bob and weave and counter and use footwork to side step and dodge because hey THAT'S FAITHFUL TO BOXING. Hell might as well let him heal after 3 minutes because that's exactly a round! And he's based on Mike Tyson, give him stances and a wide variety of punches instead of jabs, straights and uppercuts! But there's a reason why they don't do that.
