I'm curious, if you could make a single relatively small change (no, "revert all changes to 'x'" isn't a small change imo) to improve healers, what would it be?

For me, I only have level 60 healers, but already I can see how much I'm just pressing the same dps button over and over again with a single dot thrown out now and then. I don't know how much that changes, but it'd be nice to have another ability that I could press regularly (not on a 60 second CD) that did damage. That would be my one change.

Note, I know nothing about healers, but as I'm levelling all my other jobs, I'm slowly learning.
