I think they would be a bit more open if they were actually nerfing him. Darius isn't exactly the most liked character in the game, and every Silver and Bronze player would rejoice to hear of his nerfing.

As for the Apprehend becoming slower, Riot said that it was a bug they have no idea what caused or how to fix (they said they hadn't changed a single thing about Darius in that patch so it must have been something else causing it). They haven't said anything about it since so unsure what to make of it now.
