OP if you're just pressing one button while playing a healer, you're doing it wrong. All healers have a number of skills to use that are more than just "heal skill". As AST, I can be clicking 7-10 times on different things in a string of skills in a single burst. And I know SCH has more than just Succor or something. Maybe take some time to learn your skills more and take an active role in the duty you're in instead of just using Physick or spamming Ruin/Broil.
