There is a new change with how sacred shield works for Holy Pallies. Pallies can now shield multiple targets at once, however it does have three charges, with a 10 second recharge time duration. It now will also cost mana. PTR does not currently have the mana value however.
Sacred Shield
for Holy Paladins can now be active on more than one target at a time,
but the talent now costs mana, and has 3 charges with a 10-second
recharge.
I’m sure some of you are thinking why do paladins need yet another buffed shield, but blizzard is hoping to help deal with some of the Paladin shielding with the changes they’ve already made on the PTR.
It is worth noting that for Prot and Ret, Sacred Shield is now 30% less effective.
