As strange as it sounds, I hope we get nothing.

Healing as a role needs a rework and quite possibly even parts of the game itself and encounter design. That's much, much bigger than patching up a single job, like NIN. That's just not something they can do in a patch, nor should they. They need to hire staff to the class design team who actually play and understand how healers function and make some big changes.

Random tweaks would likely go badly. In terms of balance healers are doing fine. AST does not need another random buff because it's not popular enough, nor does WhM need a nerf because people play it. I know we want changes, but throwing a token potency tweak at us to keep us quiet will just throw balance out. They need to do this properly.
