well if you ask me .. they managed to actually give some thought into this changes.
for one:
And loosing 10s on stun is rather irritating. Couldn't they have taken it from imp.hammer of justice rather than JotJ?

10s out of Imp. hammer of justice would be like a nail in coffin for Ret or Holy(more like 10 or so nails). i mean really. the screams of rage would have never stopped and this time .. with a good reason. it was obvious that any change they'd do to the prot specced healers would be deep prot talents.
also the TBTL change has a nice touch. what do both PVP gear and PVE prot gear have globs in common? Stamina. what does PVE prot gear ALWAYS have in globs and PVP gear healing gear doesn't? Strength.
without the added Spell power from the TBTL prot heals will simply pale, even considering the 30% greater crits. it's a nice twist that doesn't royaly fuck PVE Protection and neither PVP Protection (not healing wise - damage wise). it's not exactly problem free since it will shift alot of power on MORE STR .. but hey.
and last but not least. the Threat nerf. yeah it's an OBVIOUS double nerf, i'm not even going to dispute that. but really now, really really .. none of you expected this? i mean the Prot pallys absolutely rule in threat any other tank and this was even before the SOV change.
