In beta, we initially had a progressive gold cost to respec. Then it was removed, replaced by a more rigid talent swapping system, which was then made more flexible with some Inscription consumables.
However, from the last PTR notes (Patch 7.0.3 PTR - Build 21935), we get a respec cost again...

(Patch notes were updated but this is still there)Specialization System Changes
- Characters can now change between any of their specializations at most any time for a progressive gold cost. Action bar configurations are saved for each specialization. As a result, Dual Specialization has been removed.
- Characters can queue up as any role that is available to their class and will automatically switch to the suitable specialization when entering the Dungeon, Raid, Battleground, or Arena without any gold cost. For example, a paladin might be questing as Retribution but queue up in Dungeon Finder as a Tank. When the paladin enters the dungeon, they will automatically switch to Protection.
What's going on? I'm confused...
EDIT: I do understand how this system works -- I simply don't understand why this system was put back in place after it was removed.
UPDATE: I've just logged in the PTR and I respecced several times with no cost at all. I wonder if these patch notes are up-to-date.
