Shunpo gets damage reduction passively now whenever it's used. As for the "useless when CC'd" thing....pretty much EVERY champ is useless when CC'd. They lowered the damage slightly of her other skills, mostly because they gave her a new active damaging skill.
Bouncing Blade actually deals more damage than it used to if you activate the mark, and although Shunpo's damage was reduced, as well as her ulti's total damage, but with the new W skill, which allows her to now AoE farm better (which makes up for the loss of the bonus gold from her passive), AND the skill refresh on kill OR ASSIST, I actually think she's a lot more reliable now, though she's not as "OMG WTF HAPPENED MY HEALTH IS GONE!" but neither is she as "ugh, Kat, someone dodge," either.
