I don't think i'ts so bad. Healing as sage, I feel like I do add a decent amount of value to my team. However, I do noticed I can get nuked easily and that I can't heal through players getting nuked by other certain classes (force lightning!). But, I think that is a balance issue that will get corrected soon. I notice others in this thread feel very similarly. Give it a bit more time for the level 50 brackets to fill.
