One of the big complaints from Shamans this expansion is that there aren’t that many instances where groups of players are stacked up enough to get the full utility out of Healing Rain.
Previously, the radius of healing rain was 10 yards. Blizzard has now increased the radius to 12 yards, which will help slightly with all the fights that require the raid to be spread out 8-10 yards. The 12 yard radius change applies to all Shaman specs.
This isn’t a huge buff, however, it is nice and might help shammies get an extra player or two in their Healing Rain. It is quite noticeable when dropping Healing Rain on the PTR though.
