Healing would be cool if they made it so that when out of combat(like how we can summon Trust NPCs) we automatically heal, but if in combat we still have to use the /heal command. It would be balanced so we can heal when out of combat but if we are fighting as something like a WHM or a BRD, doing only support actions, or we are kiting a mob around and not being hit or hitting it, we don't automatically heal since we are on an enemies hate list already.
On top of that, increasing the rate that we start to heal and the rate at which we heal once we start to would be nice, we take I think 30 seconds after we /heal before we start to gain HP or MP, which is kinda slow, I would rather it be something more like 10~15 seconds, and increasing the gain per tick would be cool too. All of this of course would mean Clear Mind would need to be changed or adjusted.
