I'd have to agree except for the Wavedashing and Analog Sheilding part. To complain that wavedashing is gone means that you still haven't cleaned that sand out of your ******. Grow up, it's a new game, and I think the new airdodging brings a lot to the game. It's comments like that that make certain casual players hate toruney players. I hope I never have to hear another person complain that wavedashing is gone.
Also, it is sad that analog sheilding is gone, but that's because of the hardware. If you were playing with wiimote or wiimote+nunchuk, you wouldn't be able to analog shield. And just because the Classic Controller can do it, still doesn't give them a big reason, because they want you to be able to play this game to it's full potential without having to go out and by soemthing. I'm not going to count Gcube in this because that's old hardware and it wouldn't look good for Nintendo to make the last gen controller look better. Not to say that you shouldn't play with it (because I most certainly do), but i'm just saying to look at it from Nintendo's point of view. Also, because analog shielding is gone, sheilds are more powerful. You can also see how that might relate to the point of "Brawl being easier for everyone" theory. But a good player wouldn't be shielding all day, so I don't really mind it to much.
But other than those, I agree with you on the other stuff. WHY IS THERE NO L-CANCELLING...AND WHY IS THERE TRIPPING?!?!?! The answer is, of course, obvious why, but I'm sure most of us have shouted out in furry at it.
