If you have ever played a Resto Shaman, you have probably played Earth Shield wars a time or two, especially if you happen to have more than 2 Resto Shamans in a raid. So of course it makes perfect sense that when they are dropping the size of the raid that they make the change to allow multiple Earth Shields to stack on a target.
This change means you could have multiple Earth Shields on a single tank for high incoming damage parts of a fight and you don’t have to worry about accidentally overwriting another healer’s Earth Shield when you go to reapply it on a tank.
No mention of Earth Shield in the patch notes. Surely you are scrapping that, it’s such a pain with multiple Shamans!
Multiple Earth Shields can stack, not a pain. (Celestalon)
So you are changing Earth Shield so 2 can be on the same target at a time finally?
Yes. (Celestalon)
This change is a long time coming, but it is a shame they didn’t make the change long ago.
