All of the raid changed a little actually.
1: the raid is now open to anyone who is level 75, their gear is scaled to epic quality
2: 1st and 3rd boss now have 22% less health across all raid difficulties
3: we get s5/s6 quality epics from the raid.
4: 1st boss Citovras has the buff/timer of his stomp upon the screen which is 9 seconds
5: easy mode of the raid and possibly future raids give 200+ Determination and 300+ bloodlust boost
as for Astral changes not sure, but will note them here if it is harder or easier.
Edit: I think Astral is a bit easier now, it can be breezed through on normal, not sure if they changed s6 though, most likely just s5.
