You realise of course that the post you're linking was made on October 14th, about 2 weeks before the GCD changes were implemented on the PTR...
GG misinformation and QQ fact checking?
Now according to this post from Drysc, the 2.3 patch is scheduled for November 13th, although they have said they will push it back if need be:

And this still hasn't been fixed on the PTR yet...I'm not saying that Blizz aren't going to fix it, Hortus has said it will be addressed, but the question I suppose is when? Before 2.3 goes live? In 2.4? We can only wait and see.
And just to prove I'm not QQ'ing - there are some things I'm really looking forward to in this patch - priests getting fear ward, as well as improved mana regen and PW:S being affected by spell damage. Also the ability to buy season 1 arena gear as a BG reward is nice. Finally the reduction in XP needed to level between 20 and 60, and the increased XP reward from quests is welcome news!
Cheers,
