I can see how both sides would view the wording. But knowing that pantheon is trying to make the healers equal in the sense of being able to perform the job that the other would do. I'm sure it means the "druids" spell jumps.
Remember this is only a glimmer of the list of spells, there are many more that could be kept behind the scenes that will work perfectly fine with this ability. I mean the wow druid at 1 point had 4 different types of heal over time spells. So there is a wide array of ways that they can make this ability work with the druid.
