Twisted Fate vs. Blind and Dodge

yes that was a change intended and noted in the initial preseason update, just like renekton stun.

Yes. This is true; it's a consistency change since it was very problematic. (Nasus' Q went through blind, while Garen's Q did not; some effects applied CC but no damage, some did damage but no CC).
