T6 was already in the game when Dragon Spine came out, it was just unfinished. And this was about 2-3 years ago?!
Oh yeah and that would have been the T5. :)

Not sure what you are trying to say. Palace of Cetriss is T6. It has been confirmed that T6 raid gear will have a higher stat budget than T5. It's also been said that there were 4 armor skins, so I'm assuming 1 each for rogue/mage/priest/soldier but all 12 classes will have stat specific gear, just the visuals for your archetype will be same, i.e. necro and hox gear will visually look the same, but necro gear will have necro stats and hox gear have hox stats. They might even add class restrictions, as they did with T5 sets.
