All tech rolls could be sped up universally, but standard rolls must be done on a character specific basis.
Personally, I don't find this to be our most important adjustment. A characters roll is part of what makes him unique. Game & Watch's abysmal roll is a weakness of his, some would argue it's a needed weakness. Yoshi's roll might match how he rolls in Yoshi's Island.
I do find that in general the newly added characters since Smash 64 get AWESOME rolls while the old cast retain OK ones. This might be Nintendo not wanting to mess with characters much, but I'm not sure it shows an honest effort to balance the characters.
And, like the others, I'm no fan of increasing throw speeds.
But 1.5 jump speeds is nice.
