"Keep Brawl stuff," "Keep Melee stuff"
...Just don't expect Falco to throw his reflector anytime soon.
This.
For me, Brawl had alot of stuff fixed that Melee just made me and my friends rage. (Biggest thing being Falcon's side-b ledge recovery spasm, which at least P:M fixed).
But there are other things that still get at me from P:M just like Melee did the same. For instance:
1. The no-backwards ledge grab (makes you think you actually landed safe on the stage, when you just fall down to your misery)
2. The insane amount of gravity you have from just plain jumping from air to platform (had so many people raging for Pit's aerial game compared on how he was from brawl) (and if you by some mistake keep pressing a jab against someone on the edge and they shield, you fall quick since you n-air'd and can't recover :/ )
3. And, personally, my biggest foe, the Melee camera. (This thing drives me dizzy, especially when it's a big stage like temple, and your bouncing around the whole stage, when you tech skills fail as the camera tries it's best to keep up, when the brawl camera just has a wide but fair view of the stage).
4. The no-instant-ledge grab from Melee (you can just abuse the edge-guarding to the point of going from 50-100+ damage in just a few smashes since you can't grab the edge just right ((especially
with C. Falcon, when you fall out of the stage you just can't come back up with that Up-B if you don't make contact with the player )))
Things that just get your bad side of attention at the game, but small compared to how drastically they've made an almost perfect balance of a true smash game as it should have been since the very beginning.
P.S. Personally I prefer Brawl's Falco, as he actually prefers the AIR! (AKA not fall quite faster than Fox in Melee, as the logic that a bird with wings falsl faster than a fully grown fox is master logic. lol
I can understand it's part of his techniques for combos and such, but that doesn't mean P:M team can't redesign him...
