As a Scholar who actually does Savage, I can confirm that healing and DPSing in A10S as a healer keeps both me and my healing partner still below the activity % and casts per minute of our tanks and DDs. So even though we're healing and DPSing (me currently ranking 68% and my healing partner 57%), we're still actually using less actions than our tanks and DDs (apart from 1). So even though you feel like you're doing a lot, your party members are probably doing even more...
