Thanks for the response - although I don't like to take "somewhere in a Fanfest talk" as a source. If there isn't either a transcript or a presentation slide stating that they're doing it, things are up for misinterpretation and getting relayed as fact when it was never actually said. (Especially if it's not being mentioned anywhere else - other interviews from the event, or reported in event summaries, or in live letters.)
That said, I recently picked up the ARR relic quest for an alt character, and wasn't required to travel to Coerthas to access the Chimaera battle. It just unlocked instantly when Gerolt said I had to go there. So along with the Crystal Tower simplifications, it's possible they're cutting down on at least minor runabout quest objectives where they can.
