Lets say I wanted to do a weird build where I entirely focused on doing lots of damage and lots of healing, while not worrying much about anything else (within reason). I know healing in dnd is notoriously not a great use of action economy, but im mostly looking to fulfill a fantasy. Specifically the ffxiv white mage playstyle, not a lot of party wide support or utility but the best healing of any healer and some of the most personal damage of any healer. What classes and subclasses should I take for this and what spells/feats would you recommend? I also don't mind lower defenses, its actually how I prefer to play healers.
